Search for L5 Earth Trojans with DECam
Larissa Markwardt, David W. Gerdes, Renu Malhotra +3
Most of the major planets in the Solar System support populations of co-orbiting bodies, known as Trojans, at their L4 and L5 Lagrange points. In contrast, Earth has only one known…
Detection of Diatomic Carbon in 2I/Borisov
Hsing Wen Lin, Chien-Hsiu Lee, David W. Gerdes +4
2I/Borisov is the first-ever observed interstellar comet (and the second detected interstellar object). It was discovered on 30 August 2019 and has a heliocentric orbital eccentric…
Birds of a Feather? Magellan/IMACS Spectroscopy of the Ultra-Faint Satellites Grus II, Tucana IV, and Tucana V
J. D. Simon, T. S. Li, D. Erkal +54
We present Magellan/IMACS spectroscopy of three recently discovered ultra-faint Milky Way satellites, Grus II, Tucana IV, and Tucana V. We measure systemic velocities of V_hel = -1…
Dark Energy Survey Year 1 results: The relationship between mass and light around cosmic voids
Y. Fang, N. Hamaus, B. Jain +74
What are the mass and galaxy profiles of cosmic voids? In this paper we use two methods to extract voids in the Dark Energy Survey (DES) Year 1 redMaGiC galaxy sample to address th…
Detection of cross-correlation between gravitational lensing and gamma rays
S. Ammazzalorso, D. Gruen, M. Regis +75
In recent years, many gamma-ray sources have been identified, yet the unresolved component hosts valuable information on the faintest emission. In order to extract it, a cross-corr…
Astrometry and Occultation predictions to Trans-Neptunian and Centaur Objects observed within the Dark Energy Survey
Martin Banda-Huarca, Julio Camargo, Josselin Desmars +59
Transneptunian objects (TNOs) are a source of invaluable information to access the history and evolution of the outer solar system. However, observing these faint objects is a diff…
