Challenges and Opportunities of Gravitational Wave Searches above 10 kHz
Nancy Aggarwal, Odylio D. Aguiar, Diego Blas +34
The first direct measurement of gravitational waves by the LIGO and Virgo collaborations has opened up new avenues to explore our Universe. This white paper outlines the challenges…
Primordial black holes and their gravitational-wave signatures
Eleni Bagui, Sebastien Clesse, Valerio De Luca +17
In the recent years, primordial black holes (PBHs) have emerged as one of the most interesting and hotly debated topics in cosmology. Among other possibilities, PBHs could explain…
Axion-Gauge Dynamics During Inflation as the Origin of Pulsar Timing Array Signals and Primordial Black Holes
Caner Unal, Alexandros Papageorgiou, Ippei Obata
We demonstrate that the recently announced signal for a stochastic gravitational wave background (SGWB) from pulsar timing array (PTA) observations, if attributed to new physics, i…
Accretion, Evaporation and Superradiance Phase Diagram of (Primordial) Black Holes and eV Scalar, Vector, Tensor Fields
Caner Unal
We obtain the accretion, evaporation and superradiance phase diagram of astrophysical and primordial black holes in the mass range . This black hole m…
Probing ultralight scalar, vector and tensor dark matter with pulsar timing arrays
Caner Unal, Federico R. Urban, Ely D. Kovetz
Pulsar timing arrays (PTAs) are sensitive to oscillations in the gravitational potential along the line-of-sight due to ultralight particle pressure. We calculate the probing power…
Unveiling cosmological information on small scales with line intensity mapping
Sarah Libanore, Caner Unal, Debanjan Sarkar +1
One of the toughest challenges in modern cosmology is to probe the small scales Mpc in the matter power spectrum and clustering. We show that such small scales…
