VVV Survey Microlensing Events in the Galactic Center Region
María Gabriela Navarro, Dante Minniti, Rodrigo Contreras Ramos
We search for microlensing events in the highly reddened areas surrounding the Galactic center using the near-IR observations with the VISTA Variables in the Vía Láctea Survey (VVV…
VIRAC: The VVV Infrared Astrometric Catalogue
L. C. Smith, P. W. Lucas, R. Kurtev +12
We present VIRAC version 1, a near-infrared proper motion and parallax catalogue of the VISTA VVV survey for 312,587,642 unique sources averaged across all overlapping pawprint and…
Searching for Faint Comoving Companions to the Centauri system in the VVV Survey Infrared Images
J. C. Beamin, D. Minniti, J. B. Pullen +7
The VVV survey has observed the southern disk of the Milky Way in the near infrared, covering 240 deg in the filters. We search the VVV Survey images in a 19…
Extreme infrared variables from UKIDSS - II. an end-of-survey catalogue of eruptive YSOs and unusual stars
P. W. Lucas, L. C. Smith, C. Contreras Pena +7
We present a catalogue of 618 high amplitude infrared variable stars (1 < DeltaK < 5 mag) detected by the two widely separated epochs of 2.2 um data in the UKIDSS Galactic plane su…
Galactic Bulge Population II Cepheids in the VVV Survey: Period-Luminosity Relations and a Distance to the Galactic Center
A. Bhardwaj, M. Rejkuba, D. Minniti +7
We present the near-infrared observations of population II Cepheids in the Galactic bulge from VVV survey. We identify 340 population II Cepheids in the Galactic bulge from VVV sur…
Pulsating stars in Centauri: Near-IR properties and period-luminosity relations
Camila Navarrete, Márcio Catelan, Rodrigo Contreras Ramos +4
Centauri (NGC~5139) contains many variable stars of different types, including the pulsating type II Cepheids, RR Lyrae and SX Phoenicis stars. We carried out a deep, wide-fiel…
