The globular cluster NGC7492 and the Sagittarius tidal stream: together but unmixed
Julio A. Carballo-Bello, Jesús M. Corral-Santana, Márcio Catelan +7
We have derived from VIMOS spectroscopy the radial velocities for a sample of 71 stars selected from CFHT/Megacam photometry around the Galactic globular cluster NGC7492. In the re…
Tails and streams around the Galactic globular clusters NGC1851, NGC1904, NGC2298 and NGC2808
Julio A. Carballo-Bello, David Martínez-Delgado, Camila Navarrete +4
We present DECam imaging for the peculiar Galactic globular clusters NGC1851, NGC1904 (M79), NGC2298 and NGC2808. Our deep photometry reveals that all the clusters have an importan…
Deep Subaru Hyper Suprime-Cam observations of Milky Way satellites Columba I and Triangulum II
Jeffrey L. Carlin, David J. Sand, Ricardo R. Munoz +9
We present deep, wide-field Subaru Hyper Suprime-Cam photometry of two recently discovered satellites of the Milky Way (MW): Columba I and Triangulum II. The color magnitude diagra…
Serendipitous discovery of RR Lyrae stars in the Leo V ultra-faint galaxy
Gustavo E. Medina, Ricardo R. Muñoz, A. Katherina Vivas +9
During the analysis of RR Lyrae stars discovered in the High cadence Transient Survey (HiTS) taken with the Dark Energy Camera at the 4-m telescope at Cerro Tololo Inter-American O…
The Fourteenth Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the extended Baryon Oscillation Spectroscopic Survey and from the second phase of the Apache Point Observatory Galactic Evolution Experiment
Bela Abolfathi, D. S. Aguado, Gabriela Aguilar +344
The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) has been in operation since July 2014. This paper describes the second data release from this phase, and the fourtee…
The SAGA Survey: I. Satellite Galaxy Populations Around Eight Milky Way Analogs
Marla Geha, Risa H. Wechsler, Yao-Yuan Mao +8
We present the survey strategy and early results of the "Satellites Around Galactic Analogs" (SAGA) Survey. The SAGA Survey's goal is to measure the distribution of satellite galax…
