Applications of machine learning in gravitational wave research with current interferometric detectors
Elena Cuoco, Marco Cavaglià, Ik Siong Heng +2
This article provides an overview of the current state of machine learning in gravitational-wave research with interferometric detectors. Such applications are often still in their…
Behind the dust veil: A panchromatic view of an optically dark galaxy at z=4.82
Nikolaj B. Sillassen, Shuowen Jin, Georgios E. Magdis +30
Optically dark dusty star-forming galaxies (DSFGs) play an essential role in massive galaxy formation at early cosmic time, however their nature remains elusive. Here we present a…
Quantum Gravitational Hair in Gravastars and Observational Tests
Italo Perrucci, Folkert Kuipers, Roberto Casadio
Using the effective field theory of quantum gravity at second order in curvature, we calculate quantum corrections to the metric of gravastars and the closely related dark energy s…
Average X-ray properties of galaxy groups. From Milky Way-like halos to massive clusters
P. Popesso, I. Marini, K. Dolag +20
This study examines the average X-ray properties of massive halos at z< 0.2, covering the largest halo mass range to date, from Milky Way-like halos to massive clusters. The analys…
The hot gas mass fraction in halos. From Milky Way-like groups to massive clusters
P. Popesso, A. Biviano, I. Marini +21
By using eROSITA data in the eFEDS area, we provide a measure of the hot gas fraction vs. halo mass relation over the largest halo mass range, from Milky Way-sized halos to massive…
The perils of stacking optically selected groups in eROSITA data. The Magneticum perspective
P. Popesso, I. Marini, K. Dolag +23
Hydrodynamical simulation predictions are often compared with observational data without fully accounting for systematics and biases specific to observational techniques. Using the…
