The VVVX quest for satellites around the Circinus galaxy

Laura D Baravalle, A. L. O'Mill, M. V. Alonso, C. Obasi et autres

Context. The Circinus galaxy is the nearest type-2 Seyfert galaxy, located at a distance of 4.2 Mpc. Its environment is challenging to explore because of the low Galactic latitudes of its location, behind the disc of the Milky Way. Aims. The long-term …

Summer simulated biogenic emissions compared to Sentinel-5P observations in Argentina

Anahi Bianco, María Fernanda García Ferreyra, M. A. Sgró, Gabriele Curci et autres

Isoprene is a biogenic volatile organic compound with significant relevance in atmospheric chemistry, as it participates in the formation of tropospheric ozone and secondary aerosols. Argentina lacks a detailed inventory of biogenic emissions, as well as continuous measurements of isoprene or volatile …

Faint galaxies in the Zone of Avoidance revealed by JWST/NIRCam

J. L. Nilo Castellón, M. V. Alonso, Laura D Baravalle, C. Villalón et autres

Context. 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 confusion noise have historically limited the detection of background galaxies in these regions, with implications for …

The VVV near-IR galaxy catalogue of the southern Galactic disc

M. V. Alonso, Laura D Baravalle, J. L. Nilo Castellón, C. Villalón et autres

Context. The distribution of galaxies in the zone of avoidance (ZoA) is incomplete due to the presence of our own Galaxy. Aims. Our research is focussed on the identification and characterisation of galaxies in the ZoA, using the new near-infrared (NIR) data …

The VISTA Variables in the Vía Láctea extended (VVVX) ESO public survey: Completion of the observations and legacy

R. K. Saito, M. Hempel, J. Alonso-García, P. W. Lucas et autres

Context. The ESO public survey VISTA Variables in the Vía Láctea (VVV) surveyed the inner Galactic bulge and the adjacent southern Galactic disk from 2009–2015. Upon its conclusion, the complementary VVV extended (VVVX) survey has expanded both the temporal as well as …

R. K. Saito, M. Hempel, J. Alonso-García, P. W. Lucas et autres

The ESO public survey VISTA Variables in the Vía Láctea (VVV) surveyed the inner Galactic bulge and the adjacent southern Galactic disk from $2009-2015$. Upon its conclusion, the complementary VVV eXtended (VVVX) survey has expanded both the temporal as well as spatial …

Galaxies in the zone of avoidance: Misclassifications using machine learning tools

P. Marchant Cortés, J. L. Nilo Castellón, M. V. Alonso, Laura D Baravalle et autres

Context. Automated methods for classifying extragalactic objects in large surveys offer significant advantages compared to manual approaches in terms of efficiency and consistency. However, the existence of the Galactic disk raises additional concerns. These regions are known for high levels of interstellar …
