On Neutron Star Mergers as the Source of r-process Enhanced Metal Poor Stars in the Milky Way
Mohammadtaher Safarzadeh, Richard Sarmento, Evan Scannapieco
We model the history of Galactic r-process enrichment using high-redshift, high-resolution zoom cosmological simulations of a Milky Way (MW) type halo. We assume that all r-process…
r-process enrichment of ultra-faint dwarf galaxies by fast merging double neutron stars
Mohammadtaher Safarzadeh, Enrico Ramirez-Ruiz, Jeff. J. Andrews +3
The recent aLIGO/aVirgo discovery of gravitational waves from the neutron star merger (NSM) GW170817 and the follow up kilonova observations have shown that NSMs produce copious am…
Modeling Star Formation as a Markov Process in a Supersonic Gravoturbulent Medium
Evan Scannapieco, Mohammadtaher Safarzadeh
Molecular clouds exhibit lognormal probability density functions (PDF) of mass densities, which are thought to arise as a consequence of isothermal, supersonic turbulence. Star for…
Modeling Photoionized Turbulent Material in the Circumgalactic Medium
Edward Buie, William Gray, Evan Scannapieco
The circumgalactic medium (CGM) of nearby star-forming galaxies show clear indications of \ion{O}{6} absorption accompanied by little to no \ion{N}{5} absorption. This unusual spec…
A limit on the warm dark matter particle mass from the redshifted 21 cm absorption line
Mohammadtaher Safarzadeh, Evan Scannapieco, Arif Babul
The recent EDGES collaboration detection of an absorption signal at a central frequency of MHz points to the presence of a significant Lyman- background by a redsh…
