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…
Origin of a massive hyper-runaway subgiant star LAMOST-HVS1 -- implication from Gaia and follow-up spectroscopy
Kohei Hattori, Monica Valluri, Norberto Castro +3
We report that LAMOST-HVS1 is a massive hyper-runaway subgiant star with mass of 8.3 Msun and super-Solar metallicity, ejected from the inner stellar disk of the Milky Way 3…
Old, Metal-Poor Extreme Velocity Stars in the Solar Neighborhood
Kohei Hattori, Monica Valluri, Eric F. Bell +1
We report the discovery of 30 stars with extreme space velocities ( 480 km/s) in the Gaia-DR2 archive. These stars are a subset of 1743 stars with high-precision parallax, large…
