Chandra and HST Observations of Radio-Selected (Wandering) Massive Black Hole Candidates in Dwarf Galaxies
Megan R. Sturm, Amy E. Reines, Anne M. Lohfink +6
We present Chandra X-ray Observatory and Hubble Space Telescope (HST) follow-up observations of 12 dwarf galaxies from Reines et al. (2020) that are potential hosts of radio-select…
Gaia GraL: Gaia gravitational lens systems IX. Using XGBoost to explore the Gaia Focused Product Release GravLens catalogue
Quentin Petit, Christine Ducourant, Eric Slezak +21
Aims. Quasar strong gravitational lenses are important tools for putting constraints on the dark matter distribution, dark energy contribution, and the Hubble-Lemaitre parameter. W…
Semi-Supervised Learning for Lensed Quasar Detection
David Sweeney, Alberto Krone-Martins, Daniel Stern +7
Lensed quasars are key to many areas of study in astronomy, offering a unique probe into the intermediate and far universe. However, finding lensed quasars has proved difficult des…
Thirteen New M Dwarf + T Dwarf Pairs Identified with WISE/NEOWISE
Federico Marocco, J. Davy Kirkpatrick, Adam C. Schneider +31
We present the discovery of 13 new widely separated T dwarf companions to M dwarf primaries, identified using WISE/NEOWISE data by the CatWISE and Backyard Worlds: Planet 9 project…
GraL spectroscopic identification of multiply imaged quasars
Priyanka Jalan, Vibhore Negi, Jean Surdej +24
Gravitational lensing is proven to be one of the most efficient tools for studying the Universe. The spectral confirmation of such sources requires extensive calibration. This pape…
The Initial Mass Function Based on the Full-sky 20-pc Census of 3,600 Stars and Brown Dwarfs
J. Davy Kirkpatrick, Federico Marocco, Christopher R. Gelino +85
A complete accounting of nearby objects -- from the highest-mass white dwarf progenitors down to low-mass brown dwarfs -- is now possible, thanks to an almost complete set of trigo…
Gaia GraL: Gaia DR2 Gravitational Lens Systems. VIII. A radio census of lensed systems
Dougal Dobie, Dominique Sluse, Adam Deller +26
We present radio observations of 24 confirmed and candidate strongly lensed quasars identified by the Gaia Gravitational Lenses (GraL) working group. We detect radio emission from…
A highly magnified gravitationally lensed red quasar at z = 2.5 with significant flux anomaly: Uncovering a missing population
E. Glikman, C. E. Rusu, S. G. Djorgovski +5
We present the discovery of a gravitationally lensed dust-reddened QSO at discovered in a survey for red QSOs by infrared selection. imaging in t…
The Environments of High Redshift QSOs
Soyoung Kim, Massimo Stiavelli, M. Trenti +9
We present a sample of -dropout candidates identified in five Hubble Advanced Camera for Surveys fields centered on Sloan Digital Sky Survey QSOs at redshift . Ou…
