The standard sirens in the gravitational wave (GW) astronomy provide us with a direct measure of the cosmological distances independent of the cosmic distance ladder. When accompanied by an electromagnetic counterpart, it can also provide a redshift measuremen…
The question of compatibility between our theory of gravity, more or less along the line of General Relativity, and basic notions of quantum physics has been a major concern. We focus, in particular, on an exact Weak Equivalence Principle and the notion of the…
Strong gravitational lensing by galaxy clusters is one of the most powerful tools to accurately probe the dark matter mass distribution in the densest regions of such structures, where multiple images are formed, and to test the currently accepted ɅCDM cosmolo…
In the space gravitational wave detection program, the locking and releasing of test mass is one of the key technologies. The test mass is locked in during the launch phase of the spacecraft and then released during the scientific exploration phase, allowing i…
This talk presents a summary of both sessions on the Galactic Center.…
We study static and spherically symmetric black hole (BH) solutions in extended Einstein- Maxwellscalar theories which is classified in a subclass of the U(1) gauge-invariant scalar-vectortensor theories. The scalar field is coupled to the vector field, which…
We find that a field with oscillations of matter in proper time has the properties of a zero-spin bosonic field. A particle observed in this field is a proper time oscillator. Neglecting all quantum effects, a proper time oscillator can mimic a point mass at r…
Gravitational waves (GWs) from compact binary coalescences are standard sirens that can probe the cosmic expansion history of the late-time Universe once the binary chirp mass-redshift degeneracy is broken. Methods for injecting redshift information into the i…
The IceCube neutrino observatory recently found an excess of TeV neutrinos at a significance of 4.2 σ associated to NGC 1068, one of the most well known nearby Seyfert galaxies. NGC 1068 was already known as a gamma-ray emitter in the GeV band, whereas only up…
The knowledge of what entered them is completely lost as black holes evaporate. This contradicts the unitarity principle of quantum mechanics and is referred to as the information loss paradox. Understanding the end stages of black hole evaporation is key to r…
An overview of highlights and discoveries from Mikhail Pavlinsky ART-XC telescope on board the SRG observatory is presented. Since 2019 SRG/ART-XC has conducted several full all sky surveys as well as a deep survey of our Galaxy. As a result, we obtained the c…
In this talk will first review some highlights of the scientific results of Insight-HXMT,China’s first X-ray astronomy satellite launched on June 15th, 2017. I will then introduce the future mission eXTP (enhanced X-ray Timing and Polarimetry), planned for lau…
We study asymptotic symmetries for 3d Chern-Simons theory as a gauge theory of so(3,2), sl_4 and sl_5 algebras. For the near horizon boundary conditions we present solutions from several projectors from Chern-Simons to the metric formulation. These solutions a…
Black holes are among the most challenging objects to study in the universe since nothing can escape from their event horizon. Fortunately, these objects leave traces by imposing their extreme gravitational pull on the surrounding matter as it falls into the b…
Our idea is to state that a particular set of values and reformulation of initial conditions for relic black holes, as stated in this manuscript , will enable using the idea of Torsion to formulate a cosmological constant and resultant Dark Energy. Relic Planc…
During the fourth observing run of the LVK collaboration, we have already seen large improvements in the results produced by the search pipelines in low-latency. We have reached new levels of sensitivity and reliability. In the quest to detect every gravitatio…
Next-generation gravitational-wave detectors will be able to explore a broad range of science case studies. Evaluating their detection and parameter-estimation capabilities is a mandatory step in the planning process. We will start by discussing currently avai…
A brief reminder of the case for particle dark matter and general search strategies will be followed by a description of the XENON dark matter program. The main part of the talk will cover details about the currently running XENONnT detector, the latest result…
The INTEGRAL hard X-ray surveys have proven to be of fundamental importance. In more than twenty years of operation, the INTEGRAL observatory has given us a sharper view of the hard X- ray sky, and provided the triggers for many follow-up campaigns from radio…
Supernova remnants (SNRs) are among the most important sources of non-thermal X-rays in the sky and likely contributors to Galactic cosmic rays and represent ideal targets to showcase the capabilities of the Imaging X-ray Polarimetry Explorer (IXPE) in perform…
With the IXPE satellite a new observational window has opened for the study of the physical properties of Pulsar Wind Nebulae. For the first time we are able to directly map the magnetic field geometry in the inner regions of these systems, where our current t…
In the early 1960s, as X-ray Astronomy was beginning to take shape, the critical role of X-ray polarimetry became apparent. By 2001, significant progress had been made, demonstrating the effective use of the photoelectric effect in gas as a breakthrough techni…
Observationally, it is well established that the masses of central black holes are tightly correlated with galaxy properties, most notably the bulge’s velocity dispersion. Cosmological hydrodynamical simulations can capture most of these correlations, but it i…
Imaging X-ray Polarimetry Explorer (IXPE), the first dedicated astrophysics mission for X-ray polarimetry, has now completed its 2-year prime mission phase, increasing the number of X-ray polarization detections from one to a few dozen, with significant conseq…
