You can't see me: Super-Eddington growth hindering X-ray detection in high-z broad-line active galactic nuclei
Alessandro Trinca, Alessandro Lupi, Francesco Haardt +1
We revisit black hole mass estimates for high-redshift broad-line active galactic nuclei (AGNs) discovered with JWST by jointly analysing their broad emission lines and their syste…
Is the overconcentration of pristine populations in Galactic globular clusters real? An N-body approach to the problem
P. Berczik, O. Sobodar, F. Flammini Dotti +5
Recent observations indicate that in some Milky Way globular clusters (GCs) pristine red giant branch (RGB) stars appear more centrally concentrated than enriched ones. This contra…
Feedback driven interactions between dark and luminous matter to explain tight galaxy scaling relations
Leen Alrawas, Andrea V. Macciò, Carlo Cannarozzo
The tight empirical correlation linking the stellar disk scale length to the dark matter scale radius has been proposed as possible evidence for a fundamental coupling…
Resolving the Unresolved Galactic Winds in Multi-phase Models. I. Methodology and Application
Xinfeng Xu, Drummond Fielding, Timothy Heckman +12
Galactic winds shape galaxy evolution; however, the outflowing gas is complex: it consists of multiple ionization phases, and its properties vary spatially. Therefore, methods that…
SDSS-V LVM: Verifying what, and where, the 'Galactic Center' Lobe is
K. Kreckel, O. V. Egorov, N. Drory +23
The so-called 'Galactic Center' Lobe (GCL) is an extended (~1 deg) radio continuum feature situated above the Galactic Plane, for which the literature contains varying claims about…
The long-term evolution of Ultra Faint Dwarf Galaxies and observational implications
Francesco Flammini Dotti, Roberto Capuzzo-Dolcetta, Giovanni Carraro +2
Context. In the Local Group, dwarf spheroidal galaxies (dSphs) and ultra-faint dwarf galaxies (UFDs) exhibit large velocity dispersions. These values are generally attributed to th…
