Selecting ultra-faint dwarf candidate progenitors in cosmological N-body simulations at high redshifts
Mohammadtaher Safarzadeh, Alexander P. Ji, Gregory A. Dooley +4
The smallest satellites of the Milky Way ceased forming stars during the epoch of reionization and thus provide archaeological access to galaxy formation at . Numerical studie…
The Fate of Gas rich Satellites in Clusters
Mohammadtaher Safarzadeh, Evan Scannapieco
We investigate the stellar mass loss of gas rich galaxies falling into clusters due to the change in the gravitational potential caused by the ram pressure stripping of their gas.…
On the Impact of Neutron Star Binaries Natal-Kick Distribution on the Galactic r-process Enrichment
Mohammadtaher Safarzadeh, Benoit Côté
We study the impact of the neutron star binaries' (NSBs) natal kick distribution on the Galactic r-process enrichment. We model the growth of a Milky Way type halo based on N-body…
Simulating Neutron Star Mergers as r-process Sources in Ultra Faint Dwarf Galaxies
Mohammadtaher Safarzadeh, Evan Scannapieco
To explain the high observed abundances of r-process elements in local ultra- faint dwarf (UFD) galaxies, we perform cosmological zoom simulations that include r-process production…
Is a top-heavy initial mass function needed to reproduce the submillimeter galaxy number counts?
Mohammadtaher Safarzadeh, Yu Lu, Christopher C. Hayward
Matching the number counts and redshift distribution of submillimeter galaxies (SMGs) without invoking modifications to the initial mass function (IMF) has proved challenging for s…
Primordial black holes as seeds of magnetic fields in the universe
Mohammadtaher Safarzadeh
Although it is assumed that magnetic fields in accretion disks are dragged from the interstellar medium, the idea is likely not applicable to primordial black holes (PBHs) formed i…
