The VVV near-IR galaxy catalogue of the southern Galactic disc
M. V. Alonso, L. D. Baravalle, J. L. Nilo Castellón +16
The distribution of galaxies in the Zone of Avoidance (ZoA) is incomplete due to the presence of our own Galaxy. Our research focused on the identification and characterisation of…
The GALEX Ultraviolet Virgo Cluster Survey (GUViCS). I: The UV luminosity function of the central 12 sq.deg
A. Boselli, S. Boissier, S. Heinis +50
The GALEX Ultraviolet Virgo Cluster Survey (GUViCS) is a complete blind survey of the Virgo cluster covering about 40 sq. deg. in the far UV (FUV, lambda_eff=1539A, Delta-lambda=44…
Discovery of a low surface brightness galaxy in the Zone of Avoidance using VVVX Deepstack imaging
J. L. Nilo-Castellón, L. Baravalle, D. Minniti +12
We report the discovery of VVVX J080705.96-273823.6, the first low-surface-brightness galaxy candidate identified in the Zone of Avoidance by the VISTA Variables in the Via Lactea…
The VVV near-IR galaxy catalogue in a Northern part of the Galactic disc
I. V. Daza-Perilla, M. A. Sgró, L. D. Baravalle +9
The automated identification of extragalactic objects in large surveys provides reliable and reproducible samples of galaxies in less time than procedures involving human interacti…
Low X-Ray Luminosity Galaxy Clusters. IV. SDSS galaxy clusters at z < 0.2
A. L. O'Mill, M. V. Alonso, C. Valotto +1
This is the fourth of a series of papers on low X-ray luminosity galaxy clusters. The sample comprises 45 galaxy clusters with X-ray luminosities fainter than 0.7 10 erg s$^…
The VVVX quest for satellites around the Circinus galaxy
L. D. Baravalle, A. L. O'Mill, M. V. Alonso +10
The Circinus galaxy is the nearest type-2 Seyfert galaxy, which is at a distance of 4.2 Mpc. Its environment is challenging to explore because it is located at low Galactic latitud…
Faint galaxies in the Zone of Avoidance revealed by JWST/NIRCam
J. L. Nilo-Castellón, M. V. Alonso, L. Baravalle +12
The Zone of Avoidance (ZoA) remains one of the last frontiers in constructing a comprehensive three-dimensional map of the Universe. Galactic extinction, stellar crowding, and conf…
Galaxies in the zone of avoidance: Misclassifications using machine learning tools
P. Marchant Cortés, J. L. Nilo Castellón, M. V. Alonso +10
Automated methods for classifying extragalactic objects in large surveys offer significant advantages compared to manual approaches in terms of efficiency and consistency. However,…
A deep near-infrared view of the Ophiuchus galaxy cluster
D. Galdeano, G. Coldwell, F. Duplancic +8
Context: The Ophiuchus cluster of galaxies, located at low latitudes in the direction of the Galactic bulge, has been relatively poorly studied in comparison with other rich galaxy…
Galaxy Peculiar Velocities and Infall onto Groups
M. L. Ceccarelli, C. Valotto, D. G. Lambas +3
We perform statistical analyses to study the infall of galaxies onto groups and clusters in the nearby Universe. The study is based on the UZC and SSRS2 group catalogs and peculiar…
The faint-end of the galaxy luminosity function in groups
R. E. Gonzalez, M. Lares, D. G. Lambas +1
We compute the galaxy luminosity function in spectroscopically selected nearby groups and clusters. Our sample comprises 728 systems extracted from the third release of the Sloan D…
LLAMA Millimeter and Submillimeter Observatory. Update on its Science Opportunities
M. Fernandez-Lopez, P. Benaglia, S. Cichowolski +11
The Large Latin American Millimeter Array (LLAMA for short) is a joint scientific and technological undertaking of Argentina and Brazil whose goal is to install and to operate an o…
The First Galaxy Cluster Discovered by the VISTA Variables in the VÃa Láctea Survey
L. D. Baravalle, J. L. Nilo Castellón, M. V. Alonso +12
We report the first confirmed detection of the galaxy cluster VVV-J144321-611754 at very low latitudes (l = 315.836, b = -1.650) located in the tile d015 of the…
