New methods for ALMA angular-scale based observation scheduling, quality assessment, and beam shaping II: refinements
Dirk Petry, María Díaz Trigo, Rüdiger Kneissl +5
The Atacama Large Millimeter/submillimeter Array remains the largest mm radio interferometer observatory world-wide. It is now conducting its 11th observing cycle. In our previous…
New methods for ALMA angular-scale based observation scheduling, quality assessment, and beam shaping
Dirk Petry, María Díaz Trigo, Rüdiger Kneissl +2
Up to now, the completion of an ALMA interferometric observation is determined based on the achievement of a given shape and size of the synthesized beam and the noise RMS in the r…
ALMA Observations of Asteroid 3 Juno at 60 Kilometer Resolution
ALMA Partnership, T. R. Hunter, R. Kneissl +67
We present Atacama Large Millimeter/submillimeter Array (ALMA) 1.3 mm continuum images of the asteroid 3 Juno obtained with an angular resolution of 0.042 arcseconds (60 km at 1.97…
First Results from High Angular Resolution ALMA Observations Toward the HL Tau Region
ALMA Partnership, C. L. Brogan, L. M. Perez +82
We present Atacama Large Millimeter/submillimeter Array (ALMA) observations from the 2014 Long Baseline Campaign in dust continuum and spectral line emission from the HL Tau region…
VISTA Variables in the Vía Láctea (VVV): Halfway Status and Results
Maren Hempel, Dante Minniti, István Dékány +89
The VISTA Variables in the Vía Láctea (VVV) survey is one of six public ESO surveys, and is now in its 4th year of observing. Although far from being complete, the VVV survey has a…
Discovery of New Companions to High Proper Motion Stars from the VVV Survey
Valentin D. Ivanov, Dante Minniti, Maren Hempel +14
[abridged] The severe crowding in the direction of the inner Milky Way suggests that the census of stars within a few tens of parsecs in that direction may not be complete. We sear…
Milky Way Demographics with the VVV Survey II. Color Transformations and Near-Infrared Photometry for 136 Million Stars in the Southern Galactic Disk
M. Soto, R. Barba, G. Gunthardt +18
The new multi-epoch near-infrared VVV survey (VISTA Variables in the Via Lactea) is sampling 562 sq. deg of the Galactic bulge and adjacent regions of the disk. Accurate astrometry…
Intergalactic stellar populations in intermediate redshift clusters
J. Melnick, E. Giraud, I. Toledo +2
A substantial fraction of the total stellar mass in rich clusters of galaxies resides in a diffuse intergalactic component usually referred to as the Intra-Cluster Light (ICL). The…
Light echoes reveal an unexpectedly cool Eta Carinae during its 19th-century Great Eruption
A. Rest, J. L. Prieto, N. R. Walborn +14
Eta Carinae (Eta Car) is one of the most massive binary stars in the Milky Way. It became the second-brightest star in the sky during its mid-19th century "Great Eruption," but the…
VVV DR1: The First Data Release of the Milky Way Bulge and Southern Plane from the Near-Infrared ESO Public Survey VISTA Variables in the Via Lactea
R. K. Saito, M. Hempel, D. Minniti +107
The ESO Public Survey VISTA Variables in the Via Lactea (VVV) started in 2010. VVV targets 562 sq. deg in the Galactic bulge and an adjacent plane region and is expected to run for…
New Galactic Star Clusters Discovered in the VVV Survey
Jura Borissova, Charles Bonatto, Radostin Kurtev +27
VISTA Variables in the V\'ıa Láctea (VVV) is one of the six ESO Public Surveys operating on the new 4-meter Visible and Infrared Survey Telescope for Astronomy (VISTA). VVV is scan…
Diffuse Intracluster Light at Intermediate Redshifts: ICL observations in a X-ray cluster at z=0.29
I. Toledo, J. Melnick, F. Selman +3
The diffuse intracluster light (ICL) contains a significant fraction of the total stellar mass in clusters of galaxies, and contributes in roughly equal proportion as the hot intra…
Discovery of VVV CL001. A Low-Mass Globular Cluster Next to UKS~1 in the Direction of the Galactic Bulge
D. Minniti, M. Hempel, I. Toledo +15
Context: It is not known how many globular clusters may have been left undetected towards the Galactic bulge. Aims: One of the aims of the VISTA Variables in the Via Lactea (VVV) S…
Low-ionization galaxies and evolution in a pilot survey up to z = 1
E. Giraud, Q. -S. Gu, J. Melnick +4
We present galaxy spectroscopic data on a pencil beam of centered on the X-ray cluster RXJ0054.0-2823 at . We study the spectral evolution of galaxies…
VISTA Variables in the Via Lactea (VVV): The public ESO near-IR variability survey of the Milky Way
D. Minniti, P. W. Lucas, J. P. Emerson +63
We describe the public ESO near-IR variability survey (VVV) scanning the Milky Way bulge and an adjacent section of the mid-plane where star formation activity is high. The survey…
