Chromatic Effects Across the Roman Focal Plane: Implications for Supernova Photometry and Measurements of Cosmological Parameters
Rujuta Purohit, Dillon Brout, Daniel Scolnic +14
Calibration uncertainties are the leading systematics in cosmological analyses using Type Ia supernovae (SNe Ia). For the \textit{Nancy Grace Roman Space Telescope (Roman)}, we qua…
Calibration-Induced Systematics in SALT3 Training and Their Impact on Dark Energy Constraints from Stage IV Supernova Surveys
Kene Anumba, David O. Jones, Richard Kessler +13
In the coming years, the Vera Rubin Observatory's Legacy Survey of Space and Time (Rubin-LSST) and the Nancy Grace Roman Space Telescope's (Roman) High Latitude Time Domain Survey…
Supermassive Dark Stars and their remnants as a possible solution to three recent cosmic dawn puzzles
Cosmin Ilie, Jillian Paulin, Andreea Petric +1
The James Webb Space Telescope (JWST) has begun to revolutionize our view of the Cosmos. The discovery of Blue Monsters (i.e., ultra-compact yet very bright high-z galaxies) and th…
Spectroscopic Supermassive Dark Star candidates
Cosmin Ilie, Sayed Shafaat Mahmud, Jillian Paulin +1
Dark Stars, i.e. early stars composed almost entirely of hydrogen and helium but powered by Dark Matter, could form in zero metallicity clouds located close to the center of high r…
UHZ1 and the other three most distant quasars observed: possible evidence for Supermassive Dark Stars
Cosmin Ilie, Katherine Freese, Andreea Petric +1
The James Webb Space Telescope (JWST) has recently uncovered a new record-breaking quasar, UHZ1, at a redshift of . This discovery continues JWST's trend of confronting th…
Supermassive Dark Star candidates seen by JWST?
Cosmin Ilie, Jillian Paulin, Katherine Freese
The first generation of stars in the Universe is yet to be observed. There are two leading theories for those objects that mark the beginning of the cosmic dawn: hydrogen burning P…
Analytic Approximations for the Velocity Suppression of Dark Matter Capture
Cosmin Ilie, Jillian Paulin
Compact astrophysical objects have been considered in the literature as dark matter (DM) probes, via the observational effects of annihilating captured DM. In this respect, Populat…
