Gravitational emissions and light curves of quasi-periodic orbits in Schwarzschild spacetime embedded in a Dehnen-type dark matter halo

Shijie Tan, Chunhua Jiang, Dan Li +3

Timelike orbits in curved spacetimes encode intrinsic information about the background geometry and serve as critical probes for investigating gravitational theories and source dis…

Topological and optical signatures of modified black-hole entropies

Ankit Anand, Kimet Jusufi, Spyros Basilakos +1

We investigate how deviations from the Bekenstein-Hawking entropy modify black-hole spacetimes through the recently proposed entropy-geometry correspondence. For four representativ…

(Lovelock) inflation: explaining the ACT data and equivalence to Higgs-Gauss-Bonnet inflation

Andrea Addazi, Yermek Aldabergenov, Daulet Berkimbayev +1

We revisit the Starobinsky model of inflation in light of recent data from the Atacama Cosmology Telescope (ACT), which indicates a potential preference for a slightly larger scala…

Analytical solutions of bound timelike geodesic orbits in effective-one-body frame

Chen Zhang, Wen-Biao Han

We derive the approximate analytical solutions of the bound timelike geodesic orbits in the effective-one-body (EOB) frame with extreme-mass ratio limit. The analytical solutions a…

GW230814: investigation of a loud gravitational-wave signal observed with a single detector

The LIGO Scientific Collaboration, The Virgo Collaboration, The Kagra Collaboration +1783

GW230814, detected by the LIGO Livingston observatory with a signal-to-noise ratio of 42.4, represents the loudest gravitational-wave signal in the GWTC-4.0 catalog. Its source is…

GWTC-4.0: Methods for Identifying and Characterizing Gravitational-wave Transients

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1809

The Gravitational-Wave Transient Catalog (GWTC) is a collection of candidate gravitational-wave transient signals identified and characterized by the LIGO-Virgo-KAGRA Collaboration…
