A New Collisional Ring Galaxy at z = 0.111: Auriga's Wheel
(2011)
We report the serendipitous discovery of a collision ring galaxy, identified as 2MASX J06470249+4554022, which we have dubbed 'Auriga's Wheel', found in a SUPRIME-CAM frame as part of a larger Milky Way survey. This peculiar ...
THE ROLE OF DARK MATTER INTERACTION IN GALAXY CLUSTERS
(WORLD SCIENTIFIC PUBL CO PTE LTDSINGAPORE, 2012)
We consider a toy del to analyze the consequences of dark matter interaction with a dark energy background on the overall rotation of galaxy clusters and the misalignment between their dark matter and baryon distributions ...
A Large-scale Kinematic Study of Molecular Gas in High-z Cluster Galaxies: Evidence for High Levels of Kinematic Asymmetry
(Astrophysical Journal, 2023-02-01)
We investigate the resolved kinematics of the molecular gas, as traced by the Atacama Large Millimeter/submillimeter Array in CO (2−1), of 25 cluster member galaxies across three different clusters at a redshift of z ∼ ...
High-energy particle interactions in the inner jet of the radio galaxy M87
(World Scientific, 2010-06)
Recent observations with the High Energy Stereoscopic System (HESS) have revealed strong and variable high-energy gamma-ray emission from the radio galaxy M87. The origin of such emission is uncertain, but the rapid ...
Halos de materia y estructura en gran escala /
(2010-03)
Las galaxias, grupos y cúmulos, representan los mayores sistemas ligados de materia, y por ello proveen información invaluable sobre el surgimiento, formación y evolución de estructuras en el universo. Es también frecuente ...
The orientation of galaxy pairs with filamentary structures: Dependence on morphology
(EDP Sciences, 2018-11)
Aims. With the aim of performing an analysis of the orientations of galaxy pair systems with respect to the underlying large-scale structure, we study the alignment between the axis connecting the pair galaxies and the ...
Abundance determination of multiple star-forming regions in the Hɪɪ galaxy SDSS J165712.75+321141.4

Mild evolution of the stellar metallicity gradients of disc galaxies
(2017)
Context. The metallicity gradients of the stellar populations in disc galaxies and their evolution store relevant information on the disc formation history and on those processes which could mix stars a posteriori, such ...
Compact groups of galaxies selected by stellar mass: the 2MASS compact group catalogue
(WILEY-BLACKWELLHOBOKEN, 2012)
We present a photometric catalogue of compact groups of galaxies (p2MCGs) automatically extracted from the Two-Micron All Sky Survey (2MASS) extended source catalogue. A total of 262 p2MCGs are identified, following the ...
