The spiral structure of the Galaxy revealed by CS sources and evidence for the 4:1 resonance
(WILEY-BLACKWELL, 2011)
We present a map of the spiral structure of the Galaxy, as traced by molecular carbon monosulphide (CS) emission associated with IRAS sources which are believed to be compact H II regions. The CS line velocities are used ...
Stochastic angular momentum slews and flips and their effect on discs in galaxy formation models
(Wiley Blackwell Publishing, Inc, 2014-08)
The angular momentum of galactic discs in semi-analytic models of galaxy formation is usually updated in time as material is accreted to the disc by adopting a constant dimensionless spin parameter and little attention is ...
GALAXIES BEHIND THE GALACTIC PLANE: FIRST RESULTS AND PERSPECTIVES FROM THE VVV SURVEY
(IOP PUBLISHING LTDBRISTOL, 2012)
VISTA Variables in the Via Lactea (VVV) is an ESO variability survey that is performing observations in near-infrared bands (ZY JHK(s)) toward the Galactic bulge and part of the disk with the completeness limits at least ...
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 ...
Low X-ray luminosity galaxy clusters – II. Optical properties and morphological content at 0.18 < z < 0.70
(Oxford University PressOxford, 2014)
This is the second of a series of papers on low X-ray luminosity galaxy clusters, in which
we present the r , g and i photometry obtained with Gemini Multi-Object Spectrograph
IMAGE at Gemini North and South telescopes ...
The principle of maximum entropy explains the cores observed in the mass distribution of dwarf galaxies
(EDP Sciences, 2020-10)
Cold dark matter (CDM) simulations predict a central cusp in the mass distribution of galaxies. This prediction is in stark contrast with observations of dwarf galaxies that show a central plateau or "core"in their density ...
Separate ways: the mass-metallicity relation does not strongly correlate with star formation rate in SDSS-IV MaNGA galaxies
(IOP Publishing Ltd, 2017)
We present the integrated stellar mass-metallicity relation (MZR) for more than 1700 galaxies included in the integral field area SDSS-IV MaNGA survey. The spatially resolved data allow us to determine the metallicity at ...
A galaxy model from Two Micron All Sky Survey star counts in the whole sky, including the plane
(Chicago, 2014-03-26)
We use the star count model of Ortiz & L´epine to perform an unprecedented exploration of the most important
Galactic parameters comparing the predicted counts with the Two Micron All Sky Survey observed star counts in
the ...
