The Lifecycle and Emission Properties of PAHs in Cosmological Hydrodynamic Galaxy Formation Simulations
Desika Narayanan, Paul Torrey, Massimiliano Parente +16
We present the first cosmological model for the lifecycle and luminous properties of PAHs in galaxies as they evolve from z=6-->0. We model 40 zoom-in galaxies, coupled with an on-…
A cosmological framework for stellar collisions at high redshift in proto-globular clusters, nuclear star clusters, and Little Red Dots
Claire E. Williams, Smadar Naoz, Sanaea C. Rose +8
Observations and cosmological simulations indicate that the early Universe hosted numerous compact, high-density stellar systems, where close encounters and physical collisions bet…
Death by Impact: Evidence for Merger-Driven Quenching in a Collisional Ring Galaxy at Cosmic Noon
Amir H. Khoram, Sirio Belli, Carlo Nipoti +7
The role of interactions and mergers in the rapid quenching of massive galaxies in the early Universe remains uncertain, largely due to the difficulty of directly linking mergers t…
The dynamical evolution of the stellar clumps in the Sparkler galaxy
Eric Giunchi, Federico Marinacci, Carlo Nipoti +4
Recent JWST observations detected stellar clumps around the z=1.4 gravitationally lensed Sparkler galaxy (of stellar mass ), with ages and metallici…
The long life of ultra diffuse galaxies inside low-density dark matter halos: the case of AGC 114905
Andrea Afruni, Federico Marinacci, Pavel E. Mancera Piña +1
It has long been known that, in the absence of a dark matter (DM) halo, galaxy discs tend to develop global gravitational instabilities that strongly modify their initial structure…
The density of the Milky Way's corona at through ram pressure stripping of the Draco dSph galaxy
Asger Grønnow, Filippo Fraternali, Federico Marinacci +4
Satellite galaxies within the Milky Way's (MW) virial radius are typically devoid of cold gas due to ram pressure stripping by the MW's corona. The density of th…
The origin of the high-velocity cloud complex C
F. Fraternali, A. Marasco, L. Armillotta +1
High-velocity clouds consist of cold gas that appears to be raining down from the halo to the disc of the Milky Way. Over the past fifty years, two competing scenarios have attribu…
Unveiling the corona of the Milky Way via ram-pressure stripping of dwarf satellites
A. Gatto, F. Fraternali, J. I. Read +3
The spatial segregation between dSphs and dIrrs in the Local Group has long been regarded as evidence of an interaction with their host galaxies. In this paper, we assume that ram-…
Fountain-driven gas accretion by the Milky Way
F. Marinacci, F. Fraternali, J. Binney +3
Accretion of fresh gas at a rate of ~ 1 M_{sun} yr^{-1} is necessary in star-forming disc galaxies, such as the Milky Way, in order to sustain their star-formation rates. In this w…
The mode of gas accretion onto star-forming galaxies
F. Marinacci, J. Binney, F. Fraternali +3
It is argued that galaxies like ours sustain their star formation by transferring gas from an extensive corona to the star-forming disc. The transfer is effected by the galactic fo…
Galactic fountains and gas accretion
F. Marinacci, J. Binney, F. Fraternali +3
Star-forming disc galaxies such as the Milky Way need to accrete $\gsim$ 1 of gas each year to sustain their star formation. This gas accretion is likely to come from t…
Stationary models for the extra-planar gas in disc galaxies
F. Marinacci, F. Fraternali, L. Ciotti +1
The kinematics of the extra-planar neutral and ionised gas in disc galaxies shows a systematic decline of the rotational velocity with height from the plane (vertical gradient). Th…
Exact density-potential pairs from complex shifted axisymmetric systems
L. Ciotti, F. Marinacci
In a previous paper the complex-shift method has been applied to self-gravitating spherical systems, producing new analytical axisymmetric density-potential pairs. We now extend th…
