The VISTA Variables in the Vía Láctea eXtended (VVVX) ESO public survey: Completion of the observations and legacy
R. K. Saito, M. Hempel, J. Alonso-García +143
The ESO public survey VISTA Variables in the Vía Láctea (VVV) surveyed the inner Galactic bulge and the adjacent southern Galactic disk from . Upon its conclusion, the c…
Astronomical Spectroscopy with Skipper CCDs: First Results from a Skipper CCD Focal Plane Prototype at SIFS
Edgar Marrufo Villalpando, Alex Drlica-Wagner, Brandon Roach +22
We present the first on-sky results from an ultra-low-readout-noise Skipper CCD focal plane prototype for the SOAR Integral Field Spectrograph (SIFS). The Skipper CCD focal plane c…
VVV-WIT-12 and its fashionable nebula: a four year long period Young Stellar Object with a light echo?
Roberto K. Saito, Bringfried Stecklum, Dante Minniti +7
We report the serendipitous discovery of VVV-WIT-12, an unusual variable source that seems to induce variability in its surrounding nebula. The source belongs to the rare objects t…
Characterization and Optimization of Skipper CCDs for the SOAR Integral Field Spectrograph
Edgar Marrufo Villalpando, Alex Drlica-Wagner, Andrés A. Plazas Malagón +14
We present results from the characterization and optimization of six Skipper CCDs for use in a prototype focal plane for the SOAR Integral Field Spectrograph (SIFS). We tested eigh…
The VISCACHA survey -- VIII. Chemical evolution history of Small Magellanic Cloud West Halo cluster
S. Saroon, B. Dias, T. Tsujimotto +12
The chemical evolution history of the Small Magellanic Cloud (SMC) has been a matter of debate for decades. The challenges in understanding the SMC chemical evolution are related t…
New SX Phe variables in the globular cluster NGC 288
E. Martinazzi, S. O. Kepler, J. E. S. Costa +4
We report the discovery of two new variable stars in the metal-poor globular cluster NGC 288, found by means of time-series CCD photometry. We classified the new variables as SX Ph…
