NGC 7097: THE ACTIVE GALACTIC NUCLEUS AND ITS MIRROR, REVEALED BY PRINCIPAL COMPONENT ANALYSIS TOMOGRAPHY
(IOP PUBLISHING LTD, 2011)
Three-dimensional spectroscopy techniques are becoming more and more popular, producing an increasing number of large data cubes. The challenge of extracting information from these cubes requires the development of new ...
The Hercules stream as seen by APOGEE-2 South
(Oxford University Press, 2018)
The Hercules stream is a group of comoving stars in the solar neighbourhood, which can potentially be explained as a signature of either the outer Lindblad resonance (OLR) of a fast Galactic bar or the corotation resonance ...
Signatures of long-lived spiral patterns.
(The Astrophysical Journal, 2013)
Newtonian acceleration scales in spiral galaxies
(WILEY-BLACKWELLHOBOKEN, 2012)
We revisit the issue of the constancy of the dark matter (DM) and baryonic Newtonian acceleration scales within the DM scale radius by considering a large sample of late-type galaxies. We rely on a Markov Chain Monte Carlo ...
Multiple chemodynamic stellar populations of the Ursa Minor dwarf spheroidal galaxy
(Oxford University Press, 2020)
We present a Bayesian method to identify multiple (chemodynamic) stellar populations in dwarf spheroidal galaxies (dSphs) using velocity, metallicity, and positional stellar data without the assumption of spherical symmetry. ...
REVISITING THE FOSSIL GROUP CANDIDATES UGC 842 AND NGC 6034
(IOP PUBLISHING LTD, 2010)
We present a new insight on NGC 6034 and UGC 842, two groups of galaxies previously reported in the literature as being fossil groups. The study is based on optical photometry and spectroscopy obtained with the CTIO Blanco ...
ROGER: Reconstructing orbits of galaxies in extreme regions using machine learning techniques
(Wiley Blackwell Publishing, Inc, 2020-01)
We present the ROGER (Reconstructing Orbits of Galaxies in Extreme Regions) code, which uses three different machine learning techniques to classify galaxies in, and around, clusters, according to their projected phase-space ...
galkin: A new compilation of Milky Way rotation curve data
(2017-01-01)
We present galkin, a novel compilation of kinematic measurements tracing the rotation curve of our Galaxy together with a tool to treat the data. The compilation is optimised to Galactocentric radii between 3 and 20 kpc ...
