The VMC survey -- LIII. Data release #7. Complete survey data and data from additional programmes
M. -R. L. Cioni, N. J. G. Cross, V. Ripepi +29
The near-infrared YJKs Visual and Infrared Survey Telescope for Astronomy (VISTA) survey of the Magellanic Clouds (VMC) is complete and there are also data from additional programm…
The VMC Survey : LI. Classifying extragalactic sources using a probabilistic random forest supervised machine learning algorithm
Clara M. Pennock, Jacco Th. van Loon, Maria-Rosa L. Cioni +10
We used a supervised machine learning algorithm (probabilistic random forest) to classify ~130 million sources in the VISTA Survey of the Magellanic Clouds (VMC). We used multi-wav…
New quasars behind the Magellanic Clouds. II. Spectroscopic confirmation of 136 near-infrared selected candidates
Valentin D. Ivanov, Maria-Rosa L. Cioni, Michel Dennefeld +6
Quasi-stellar objects (QSOs) are a basis for an absolute reference system for astrometric studies. There is a need for creating such system behind nearby galaxies, to facilitate th…
A Galactic Eclipse: The Small Magellanic Cloud is Forming Stars in Two, Superimposed Systems
Claire E. Murray, Sten Hasselquist, Joshua E. G. Peek +22
The structure and dynamics of the star-forming disk of the Small Magellanic Cloud (SMC) have long confounded us. The SMC is widely used as a prototype for galactic physics at low m…
VIS3COS: II. Nature and nurture in galaxy structure and morphology
Ana Paulino-Afonso, David Sobral, Behnam Darvish +7
We study the impact of local density and stellar mass on the morphology of ~500 quiescent (Q) and SFGs from the VIS3COS survey. We perform B/D decomposition of the SBPs and find ~4…
