Now that detection of gravitational-wave signals from the coalescence of extra-galactic
compact binary star mergers has become nearly routine, it is intriguing to consider other …

The birth of gravitational wave astronomy was triggered by the first detection of a signal
produced by the merger of two compact objects (also known as a compact binary …

We present results of an all-sky search for continuous gravitational waves which can be
produced by spinning neutron stars with an asymmetry around their rotation axis, using data …

We use the state-of-the-art data on cosmic chronometers (CCH) and the Pantheon+
compilation of supernovae of Type Ia (SNIa) to test the constancy of the SNIa absolute …

We present a directed search for continuous gravitational wave (CW) signals emitted by
spinning neutron stars located in the inner parsecs of the Galactic Center (GC). Compelling …

We present the angular diameter distance measurement obtained with the baryonic acoustic
oscillation (BAO) feature from galaxy clustering in the completed Dark Energy Survey …

Seven years after the first direct detection of gravitational waves, from the collision of two
black holes, the field of gravitational wave astronomy is firmly established. A first detection of …

We study weak gravitational lensing convergence maps produced from the MillenniumTNG
simulations by direct projection of the mass distribution on the past backwards lightcone of a …

We study the electrodynamics of a kinetically mixed dark photon cloud that forms through
superradiance around a spinning black hole, and design strategies to search for the …

Gravitational signatures of black hole superradiance are a unique probe of ultralight
particles that are weakly coupled to ordinary matter. The existence of an ultralight boson …
