Euclid Quick Data Release (Q1): Disc breaks highlight the structural evolution of galaxies through time
Euclid Collaboration, P. M. Sanchez-Alarcon, J. Román +302
Changes in the slope of the radial surface brightness profiles of disc galaxies, or disc breaks, encode valuable information about the processes driving disc formation and growth.…
Orbital evolution of asymmetric binaries within accreting environments
Albert Radulea, Marcelo E. Rubio, Konstantinos Kritos +1
Extreme mass-ratio inspirals embedded in accretion disks provide a natural arena for studying the interplay between relativistic orbital dynamics and environmental effects. In this…
Investigating the formation channel of GW231123: Population III stars or hierarchical mergers?
Federico Angeloni, Konstantinos Kritos, Raffaella Schneider +5
The gravitational wave event GW231123, with component black hole masses lying within or above the pair-instability mass gap, poses a significant challenge to current stellar evolut…
Predicting intermediate-mass black hole formation in star clusters with machine learning
Konstantinos Kritos, Digvijay Wadekar, Emanuele Berti
Whether intermediate-mass black holes reside in nearby star clusters has remained contested for decades. We address this question by training neural network and random forest regre…
Toward Black Hole Stars: supermassive black hole growth in nuclear clusters via stellar-object and gas accretion
Konstantinos Kritos, Joseph Silk
Supermassive black hole (SMBH) growth plausibly occurs via runaway astrophysical black hole mergers in nuclear star clusters that form intermediate mass black hole seeds at high re…
Kick matters: The impact of a new recoil model on the retention of hierarchical black-hole remnants in globular clusters
Tousif Islam, Digvijay Wadekar, Konstantinos Kritos
In globular clusters, hierarchical mergers are among the most promising pathways to forming massive black holes such as GW231123. A key factor determining whether a merger-remnant…
