Recently discovered long-period pulsars (LPPs), namely PSR J0901–4046 (76 s), GLEAM-X J162759.5– 523504.3 (1091 s), and GPM J1839–10 (1318 s), have rotational periods much longer than those of radio pulsars and other isolated neutron star populations. LPPs exh…
We have investigated the evolutionary links between the isolated neutron star populations namely radio pulsars (RPs), anomalous X-ray pulsars (AXPs), soft gamma repeaters (SGRs), dim isolated neutron stars (XDINs), high-magnetic-field RPs (HBRPs), central comp…
More than a century ago, Albert Einstein presented his general theory of gravitation. One of the predictions of this theory is that not only particles and objects with mass, but also the quanta of light, photons, are tied to the curvature of space-time, and th…
University of Birmingham We present a correlation observed in the afterglows of long duration Gamma-ray Bursts (GRBs) between the initial luminosity and average afterglow decay rate. We will show how this correlation, initially found at optical and X-ray wavel…
In this talk, we will explore the theoretical foundations of binary black holes and the revolutionary simulations in numerical relativity that have deepened our understanding of these objects. We will also showcase the remarkable achievements in observational…

Using a set of general-relativistic magnetohydrodynamics simulations that include proper neutrino transfer, we assess for the first time the role played by the fallback accretion onto the remnant from a binary neutron-star merger over a timescale of hundreds o…

Geometric optics limit is considered to be a good-enough approximation for the calculation of distances and image distortions in curved spacetime. It is usually assumed that spherical waves are emitted from a point source and we observe a section of the wavefr…
We review the contribution of undetected extragalactic sources to the cosmic microwave background (CMB) radiation, from radio to sub-millimetre wavelengths. As demostrated by very recent analyses, Active Galactic Nuclei (AGN) is the dominant population in this…
We will talk about the emergence of new sciences such as “Gravitational-wave astronomy”, “Neutrino extragalactic astronomy”, “Transient radio astronomy”, “Fast Transient X-ray Astronomy”.…

Fast radio bursts (FRBs) are enigmatic millisecond-duration pulses of radio light observed across cosmological distances. Their origins and emission mechanisms remain unclear, making FRBs one of the most intriguing new mysteries in astrophysics. The Canadian H…
The eROSITA X-ray satellite has revealed two gigantic bubbles extending to ~80° above and below the Galactic center (GC). The morphology of these ‘eROSITA bubbles’bears a remarkable resemblance to the Fermi bubbles previously discovered by the Fermi Gamma-ray…
The Bopp-Podolsky theory is a gauge-invariant and Lorentz-invariant theory of electromagnetism that introduces a new hypothetical constant of Nature with the dimension of a length, called the Bopp length. The theory was introduced by Bopp in 1940, and independ…
The Galactic X-ray black hole candidate GRS 1915+105 exhibits high-frequency quasi-periodic oscillations (HFQPOs) at ~ 67 Hz only during the radio-quiet ‘softer’ variability classes. We have studied the long-term X-ray variability from 1996 to 2017 using obser…
The launch of the Einstein Probe mission in January 2024 has marked a significant leap forward in the exploration of the transient X-ray Universe. Led by the Chinese Academy of Sciences and in collaboration with the European Space Agency, the Max Planck Instit…
A panorama of the current historiography on the Supernova of 1054 is outlined. Shklovsky (1968), and Murdin (1985) show how the interpretation of this phenomenon converged on a Su-pernova event. Here we reconsider the historical data, assuming a Gamma-Ray Burs…
We study the statistical fluctuations (such as the variance) of causal set quantities, with particular focus on the causal set action. To facilitate calculating such fluctuations, we develop tools to account for correlations between causal intervals with diffe…
Supermassive black hole binaries (SMBHBs) represent the latest stage in the hierarchical growth of massive galaxies through major mergers. In these systems, accretion onto the black holes is expected to form two individual accretion disks around each black hol…
In less than two years since the release of the first data, the James Webb Space Telescope has revolutionised our knowledge and understanding of the Universe. Thanks to its unprecedented collecting area and IR sensitivity, JWST has allowed us to study the atmo…
Novel proposal is made for candidate Fuzzy dark matter.Interestingly it has connections to primordial black holes which can seed supermassive black hole and play critical role in galaxy formation.…
GEO 600 has been operating as a gravitational wave detector routinely since before the advanced detector era in mode known as “astrowatch”. While exploring new technologies in large scale interferometry we keep the detector in an operational state allowing for…
Gamma-ray bursts (GRBs) have been observed at very high redshifts, up to 9.4, and can be a crucial astrophysical object for studying the evolutionary history of the universe. However, the rapid dimming of their afterglows, combined with the constrained availab…
The huge luminosity, the redshift distribution extending at least up to z∼10 and the association with the explosive death of very massive stars make long GRBs (i.e., those lasting up to a few minutes) potentially extremely powerful probes for shedding light on…
