High-Redshift Galactic Outflows: Orientation Effects, Kinematics, and Metallicity in TNG50 and SERRA
Ivan Kostyuk, Stefano Carniani, Mahsa Kohandel +1
Context: Recently, JWST/NIRSpec observations have provided the first detections of warm ionised outflows in low-mass galaxies at high redshifts (z>3), revealing an occurrence rate…

Influence of mergers on LyC escape of high redshift galaxies
Ivan Kostyuk, Benedetta Ciardi
Aims: We investigate the impact of galaxy mergers on the Lyman Continuum (LyC) radiation escape, fesc, from high-redshift galaxies. Methods: We post-process ~ 6e5 galaxies (redshif…

Physically motivated modeling of LyC escape fraction during reionization
Ivan Kostyuk, Benedetta Ciardi, Andrea Ferrara
Aims: We present an analysis of the Lyman continuum (LyC) escape fraction of high redshift galaxies using an analytic post-processing approach. Methods: We apply the model to 600,0…
