Stellar populations of the newly discovered satellites of the Milky Way .
(2008)
We have carried out an extensive observing campaign on the new dwarf spheroidal galaxies (dSphs) recently discovered by the SDSS, with the aim of characterizing their stellar populations and structural properties, as well ...
PHANGS-ALMA: arcsecond CO(2-1) imaging of nearby star-forming galaxies
(IOP, 2021)
We present PHANGS-ALMA, the first survey to map CO J = 2 -> 1 line emission at similar to 1 '' similar to 100 pc spatial resolution from a representative sample of 90 nearby (d less than or similar to 20 Mpc) galaxies that ...
THE LICK/SDSS LIBRARY. II. [Ca/Fe] AND [Mg/Fe] IN F, G, AND K STARS FROM SDSS-DR7
(The Astrophysical Journal, 2011)
The Araucaria project - improving stellar distance indicators
(Kurtz, D.Pollard, K., 2004)
We present first results of an optical wide field imaging survey of the galaxies NGC 300, NGC 6822, WLM and Phoenix, performed
as part of the Araucaria Project, a long-term observational program recently initiated at the ...
Are the hosts of gamma-ray bursts sub-luminous and blue galaxies?
(EDP Sciences, 2003-03)
We present K-band imaging observations of ten gamma-ray burst (GRB) host galaxies for which an optical and/or radio afterglow associated with the GRB event was clearly identified. Data were obtained with the Very Large ...
BAT AGN Spectroscopic Survey. XX. Molecular Gas in Nearby Hard-X-Ray-selected AGN Galaxies
(2021)
We present the host-galaxy molecular gas properties of a sample of 213 nearby (0.01.<.z.<.0.05) hard-X-rayselected active galactic nucleus (AGN) galaxies, drawn from the 70-month catalog of Swift's Burst Alert Telescope ...
VVV DR1: The first data release of the Milky Way bulge and southern plane from the near-infrared ESO public survey VISTA variables in the Via Lactea
(EDP SCIENCES S ALES ULIS CEDEX A, 2012)
Context. The ESO public survey VISTA variables in the Via Lactea (VVV) started in 2010. VVV targets 562 sq. deg in the Galactic bulge and an adjacent plane region and is expected to run for about five years. Aims. We ...
Influencia de la metalicidad en la Ley de Leavitt
(Universidad de los AndesFísicaFacultad de CienciasDepartamento de Física, 2023-01-20)
En este trabajo se determinó la distancia y el exceso de color interno de las galaxias NGC 6822, NGC 7793, WLM, NGC 3109 y NGC 300 mediante la Ley de Leavitt (LL) en filtros VIJK. La relación lineal en un filtro dado de ...
