Unveiling the nature of 12 new low-luminosity Galactic Globular Cluster Candidates
E. R. Garro, D. Minniti, B. Alessi +10
The Galactic globular cluster system is incomplete, especially in the low latitude regions of the Galactic bulge and disk. We report the physical characterization of twelve star cl…
Resolved Gaia Triples
Andrei Tokovinin
A sample of 392 low-mass hierarchical triple stellar systems within 100 pc resolved by Gaia as distinct sources is defined. Owing to the uniform selection, the sample is ideally su…
The Solar Neighborhood XLIX: Nine Giant Planets Orbiting Nearby K Dwarfs, and the CHIRON Spectrograph's Radial Velocity Performance
Leonardo A. Paredes, Todd J. Henry, Samuel N. Quinn +5
We report initial results of a large radial velocity survey of K dwarfs up to a distance of 50 pc from the Solar System, to look for stellar, brown dwarf, and jovian planets using…
TOI-712: a system of adolescent mini-Neptunes extending to the habitable zone
Sydney Vach, Samuel N. Quinn, Andrew Vanderburg +40
As an all-sky survey, NASA's mission is able to detect the brightest and rarest types of transiting planetary systems, including young planets that enable study of the evolu…
Clash of Titans: a MUSE dynamical study of the extreme cluster merger SPT-CL J0307-6225
D. Hernández-Lang, A. Zenteno, A. Diaz-Ocampo +23
We present VLT/MUSE spectroscopy, along with archival Gemini/GMOS spectroscopy, Magellan/Megacam imaging, and Chandra X-ray emission for SPT-CL J0305-6225, a z=0.58 major merging g…
Cosmic Shear in Harmonic Space from the Dark Energy Survey Year 1 Data: Compatibility with Configuration Space Results
H. Camacho, F. Andrade-Oliveira, A. Troja +96
We perform a cosmic shear analysis in harmonic space using the first year of data collected by the Dark Energy Survey (DES-Y1). We measure the cosmic weak lensing shear power spect…
