All-Sky Faint DA White Dwarf Spectrophotometric Standards for Astrophysical Observatories: The Complete Sample
Tim Axelrod, Abhijit Saha, Thomas Matheson +14
Hot DA white dwarfs have fully radiative pure hydrogen atmospheres that are the least complicated to model. Pulsationally stable, they are fully characterized by their effective te…
Perfecting our set of spectrophotometric standard DA white dwarfs
A. Calamida, T. Matheson, E. W. Olszewski +17
We verified for photometric stability a set of DA white dwarfs with Hubble Space Telescope magnitudes from the near-ultraviolet to the near-infrared and ground-based spectroscopy b…
A classification algorithm for time-domain novelties in preparation for LSST alerts: Application to variable stars and transients detected with DECam in the Galactic Bulge
Monika D. Soraisam, Abhijit Saha, Thomas Matheson +8
With the advent of the Large Synoptic Survey Telescope (LSST), time-domain astronomy will be faced with an unprecedented volume and rate of data. Real-time processing of variables…
The not so simple stellar system Omega Cen. II. Evidence in support of a merging scenario
Annalisa Calamida, Alice Zocchi, Giuseppe Bono +7
We present multi-band photometry covering 5° 5°across Cen collected with the Dark Energy Camera, combined to Hubble Space Telescope and Wide Field Imager data fo…
Photometry and spectroscopy of faint candidate spectrophotometric standard DA white dwarfs
A. Calamida, T. Matheson, A. Saha +14
We present precise photometry and spectroscopy for 23 candidate spectrophotometric standard white dwarfs. The selected stars are distributed in the Northern hemisphere and around t…
unVEil the darknesS of The gAlactic buLgE (VESTALE)
G. Bono, M. Dall'Ora, M. Fabrizio +55
The main aim of this experiment is to provide a complete census of old (t > 10 Gyr, RR Lyrae, type II Cepheids, red horizontal branch), intermediate age (red clump, Miras) and youn…
