China’s FAST telescope finds key evidence for existence of nanohertz gravitational waves

China’s Five-hundred-meter Aperture Spherical Radio Telescope (FAST) recently found key evidence for the existence of nanohertz gravitational waves.
The research was conducted by the Chinese Pulsar Timing Array (CPTA) collaboration, which comprises researchers from the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC) and other institutes. Their findings were published online in the academic journal Research in Astronomy and Astrophysics (RAA) on June 29.
The finding indicates China’s leading position in the world in terms of the studies on nanohertz gravitational waves.
According to Albert Einstein’s theory of general relativity, space-time is curved. Acceleration of massive objects disturbs the surrounding space-time and produces “ripples” which are known as gravitational waves.
Li Kejia, a researcher with the NAOC, told People’s Daily that the detection of nanohertz gravitational waves helps astronomers better understand the origins of the universe.
The signals of gravitational waves are extremely weak, but they offer a direct method for probing masses that do not emit light. Therefore, astronomers have long aimed to detect and use gravitational waves to aid in the observation of the universe.
Objects of greater mass produce gravitational waves of lower frequency. “For example, the most massive celestial body in the universe, the supermassive black hole binaries in the center of galaxies, mainly generate gravitational waves in the nanohertz band,” said Li.
Using nanohertz gravitational waves in cosmic observation is thus hugely important in studying key problems in contemporary astrophysics such as supermassive black holes, the history of galaxy mergers, and the formation of large-scale structures in the universe. Global physicists and astronomers have been racing to detect nanohertz gravitational waves.
Xu Heng, associate researcher with the NAOC noted that the detection of nanohertz gravitational waves can be very challenging due to their extremely low frequency, where the corresponding period can be as long as several years and wavelengths up to several light-years.
“Using FAST-like large radio telescopes to conduct long-term timing observation of millisecond pulsars with extreme rotational stability is the only known method for effectively detecting nanohertz gravitational waves,” he added.
Regional pulsar timing array collaborations, including the North American Nanohertz Observatory for Gravitational Waves, the European Pulsar Timing Array and the Australian Parkes Pulsar Timing Array, have been collecting pulsar timing data for more than 20 years, with the aim of detecting nanohertz gravitational waves.
Taking advantage of FAST’s high sensitivity, the CPTA research team monitored 57 millisecond pulsars, which formed a Galactic-scale gravitational wave detector sensitive to nanohertz gravitational waves. They found key evidence for quadrupole correlation signatures compatible with the prediction of nanohertz gravitational waves at a 4.6-sigma statistical confidence level(with a false alarm probability of two in a million).
The team used independently developed data analysis software and data processing algorithms to achieve its breakthrough at the same time as other international groups. Independent data processing pipelines produced compatible results.
Luis C.Ho, Chair Professor of Peking University noted that it was a scientific prediction that the mergers of supermassive blackholes produce nanohertz gravitational waves, and this long-anticipated prediction has finally been proved by the CPTA research team.
Ho called the finding an important scientific breakthrough that carries lasting and huge significance. It not only has profound impacts on the study of galaxy evolution and supermassive blackholes, but also has opened a brand-new window for gravitational-wave astrophysics, he noted.

 EXPOSED: Group Raises Alarm Over Alleged 2027 Power Deal Linking Akume, Atiku, Ortom and Aondoakaa

Published

on

ABUJA — A fresh political controversy has erupted ahead of the 2027 general elections as the International Centre for Transparency Nigeria (ICTN) alleges the existence of a high-level political arrangement involving key opposition figures and influential actors within Benue State politics.

The group, during a press conference held at the prestigious Sheraton Hotel, Abuja, and addressed by its National Leader, Prof. Joseph Vershima, alleged that a strategic alliance is being negotiated to reshape the political landscape of Benue State ahead of the 2027 elections.

According to ICTN, the alleged arrangement involves the Secretary to the Government of the Federation (SGF), Senator George Akume, former Benue State Governor Samuel Ortom, former Vice President Atiku Abubakar, and former Attorney-General of the Federation, Chief Mike Kaase Aondoakaa.

The group claimed that the alleged political deal is designed to influence both the presidential and governorship contests in Benue State, warning that it could have far-reaching consequences for the electoral fortunes of the All Progressives Congress (APC) and President Bola Ahmed Tinubu in the state.

Alleged “Benue Political Deal”

ICTN alleged that elements within the Benue State chapter of the Peoples Democratic Party (PDP) have entered into an understanding to support the presidential ambition of Atiku Abubakar ahead of 2027.

The group further alleged that Chief Mike Kaase Aondoakaa, whom it described as a long-standing political associate of Atiku Abubakar, has played a key role in building a bridge between former Governor Ortom’s political structure and a faction of the APC allegedly loyal to Senator George Akume.

According to the organization, part of the alleged arrangement is that Atiku Abubakar would provide financial support for the PDP governorship candidate in Benue State, while Senator George Akume’s political structure and elements within the PDP would support and mobilize for Atiku’s presidential campaign.

The group questioned the political implications of such an arrangement, asking whether those involved would ultimately prioritize the interest of the APC and President Bola Ahmed Tinubu or pursue a separate political agenda ahead of 2027.

Warning To President Tinubu

The pressure group warned that any alleged collaboration aimed at weakening the APC’s support base in Benue could directly affect President Tinubu’s chances of retaining the state during the 2027 presidential election.

“Beyond the governorship contest, this development has implications for the presidential election because Benue remains a strategic state in the North Central,” the group stated.

ICTN urged President Bola Ahmed Tinubu and the national leadership of the APC to pay close attention to internal political dynamics, alleging that unresolved alliances and conflicting interests within the party could pose challenges during the election.

Echoes Of 2007 Political Realignment

The organization also drew parallels with the 2007 presidential election, alleging that Senator George Akume’s political decisions at the time favoured Atiku Abubakar’s presidential bid against the preferred candidate of the ruling establishment.

It questioned whether a similar political realignment could emerge again in 2027, stating that history must not be allowed to repeat itself.

Awaiting Responses

As of the time of filing this report, Senator George Akume, former Governor Samuel Ortom, Chief Mike Kaase Aondoakaa, and representatives of Atiku Abubakar had not publicly responded to the allegations.

This publication has not independently verified the claims made by ICTN and continues to seek documentary evidence and responses from all parties mentioned.

However, the allegations have added a new dimension to the unfolding political calculations ahead of the 2027 general elections, with Benue State increasingly becoming a focal point in Nigeria’s emerging political contest.

Uzodinma Distances Self From Criticism of Davido, Says Singer ‘Remains My Son’

Published

on

Imo State Governor and Chairman of the Progressive Governors Forum (PGF), Hope Uzodinma, has distanced himself from comments critical of popular singer David Adeleke, popularly known as Davido, insisting that the artiste “remains my son.”

Uzodinma, who also chairs the All Progressives Congress (APC) Osun Governorship Campaign Council, said he did not authorise Ambrose Nwogwugwu or any other individual to speak on his behalf regarding the singer.

The clarification was contained in a statement issued on Friday by the governor’s Chief Press Secretary and Special Adviser on Media, Oguwike Nwachuku.

The statement followed remarks reportedly made by Nwogwugwu after Davido appealed for the August 15 Osun State governorship election to be conducted in a peaceful, free and fair manner.

Davido, who is a nephew of Osun State Governor Ademola Adeleke, had called on Uzodinma to ensure that the election is credible and violence-free.

Reacting to the controversy, Uzodinma said the comments attributed to Nwogwugwu were his personal opinions and should not be interpreted as representing his views or those of the APC Osun Governorship Campaign Council.

“Davido remains my son,” the governor stated, reaffirming his relationship with the award-winning musician.

Uzodinma also clarified that while he is actively campaigning for the APC governorship candidate, Asiwaju Munirudeen Bola Oyebamiji, he is not a registered voter in Osun State and is only participating in the campaign in support of the party.

He reiterated the APC’s commitment to a peaceful, free, fair and credible governorship election, adding that it is common in democratic systems for party leaders to campaign for candidates outside the states where they are registered to vote.

The governor urged Davido, residents of Osun State and the general public to disregard the comments credited to Nwogwugwu, saying the clarification was necessary to prevent misunderstanding ahead of the election.
