RELICS: Strong Lensing Analysis of MACS J0417.5-1154 and Predictions for Observing the Magnified High-Redshift Universe with JWST
Guillaume Mahler, Keren Sharon, Carter Fox +37
Strong gravitational lensing by clusters of galaxies probes the mass distribution at the core of each cluster and magnifies the universe behind it. MACS J0417.5-1154 at z=0.443 is…
RELICS: High-Resolution Constraints on the Inner Mass Distribution of the z=0.83 Merging Cluster RXJ0152.7-1357 from strong lensing
Ana Acebron, May Alon, Adi Zitrin +37
Strong gravitational lensing (SL) is a powerful means to map the distribution of dark matter. In this work, we perform a SL analysis of the prominent X-ray cluster RXJ0152.7-1357 (…
The initial mass function in the Coma Berenices dwarf galaxy from deep near-infrared HST observations
Mario Gennaro, Marla Geha, Kirill Tchernyshyov +6
We use deep WFC3/IR imaging to study the Initial Mass Function (IMF) of the ultra faint dwarf galaxy Coma Berenices (Com Ber). Our observations reach the lowest stellar mass…
RELICS: Strong-lensing analysis of the massive clusters MACS J0308.9+2645 and PLCK G171.9-40.7
Ana Acebron, Nathália Cibirka, Adi Zitrin +37
Strong gravitational lensing by galaxy clusters has become a powerful tool for probing the high-redshift Universe, magnifying distant and faint background galaxies. Reliable strong…
RELICS: A Strong Lens Model for SPT-CLJ0615-5746, a z=0.972 Cluster
Rachel Paterno-Mahler, Keren Sharon, Dan Coe +30
We present a lens model for the cluster SPT-CLJ06155746, which is the highest redshift () system in the Reionization of Lensing Clusters Survey (RELICS), making it the…
Chemically-dissected rotation curves of the Galactic Bulge from Main Sequence proper motions
William I. Clarkson, Annalisa Calamida, Kailash C. Sahu +9
We report results from an exploratory study implementing a new probe of Galactic evolution using archival Hubble Space Telescope imaging observations. Precise proper motions are co…
RELICS: Strong Lensing analysis of the galaxy clusters Abell S295, Abell 697, MACS J0025.4-1222, and MACS J0159.8-0849
Nathália Cibirka, Ana Acebron, Adi Zitrin +37
We present a strong-lensing analysis of four massive galaxy clusters imaged with the Hubble Space Telescope in the Reionization Lensing Cluster Survey. We use a Light-Traces-Mass t…
Evidence of a non universal stellar Initial Mass Function. Insights from HST optical imaging of 6 Ultra Faint Dwarf Milky Way Satellites
Mario Gennaro, Kirill Tchernyshyov, Thomas M. Brown +9
Using deep HST/ACS observations, we demonstrate that the sub-solar stellar initial mass function (IMF) of 6 ultra-faint dwarf Milky Way Satellites (UFDs) is more bottom light than…
A Candidate Galaxy Strongly Lensed into a Spatially Resolved Arc
Brett Salmon, Dan Coe, Larry Bradley +27
The most distant galaxies known are at z~10-11, observed 400-500 Myr after the Big Bang. The few z~10-11 candidates discovered to date have been exceptionally small- barely resolve…
