Juan Carlos Beamin,Dante Minniti,Mariusz Gromadzki,Radostin Kurtev,Valentin D. Ivanov,Yuri Beletsky,Philip W. Lucas,Roberto K. Saito,Jura Borissova +8 more
TL;DR: In this article, the Vista Variables in the V\'ia L\'actea (VVV), a near-infrared (NIR) multiwavelength (Z Y J H Ks) multi-epoch (Ks) ESO Public Survey mapping the Milky Way bulge and southern Galactic plane to search for nearby brown dwarfs (BDs) was used.

TL;DR: In this article, a sample of 404 RR Lyrae of type ab stars was identified across a thin slice of the 4$^{\rm th}$ Galactic quadrant, and the sample's spatial distribution presented evidence of density enhancements and substructure that warrants further investigation.
Journal ArticleDOI
A high-resolution radio survey of Class I protostars
TL;DR: In this article, a survey of low-mass Class I protostars in the cm continuum was conducted, and seven sources in the Taurus star formation region were observed with the VLA at 0.25-arcsec resolution.

TL;DR: In this paper, the authors verified nearly 5000 periodic transit-like signals against astrophysical and instrumental false positives yielding 1108 viable new transiting planet candidates, bringing the total count up to over 2300.

Mercer 5: a probable new globular cluster in the Galactic bulge
Andy Longmore,R. Kurtev,Philip W. Lucas,Dirk Froebrich,R. de Grijs,Valentin D. Ivanov,Thomas J. Maccarone,Jura Borissova,L. Ker +8 more
TL;DR: In this paper, a detailed study of a dust-obscured Galactic star cluster Mercer 5 (MCM2005b] 5) in an extremely crowded field in the Milky Way Near-infrared (near-IR) photometry from United Kingdom Infrared Digital Sky Surveys (UKIDSS) and the Son of ISAAC on the New Technology Telescope (SofI/NTT), combined with near-IR spectroscopy also from SofI, indicates that it is almost certainly a Galactic globular cluster, located at the edge of the Galactic bulge.
