(Universidad de Chile, 2019)En el presente trabajo estudio la morfología y cinemática de dos muestras de galaxias a bajo y alto corrimiento al rojo (redshift). Analizo la cinemática interna de estas galaxias con objetivo de encontrar posibles ...
-
(IOP Publishing, 2018)Star formation is a multi-scale process that requires tracing cloud formation and stellar feedback within the local (less than or similar to kpc) and global galaxy environment. We present first results from two large ...
-
(Institute of Physics Publishing, 2018)Modern extragalactic molecular gas surveys now reach the scales of star-forming giant molecular clouds (GMCs; 20–50 pc). Systematic variations in GMC properties with galaxy environment imply that clouds are not ...
-
(2015-08-01)We develop a simple analytical model that tracks galactic metallicities governed by star formation and feedback to gain insight from the observed galaxy stellar mass–metallicity relations over a large range of stellar ...

-
(Institute of Physics, 2017)We compare the structure of molecular gas at 40pc resolution to the ability of gas to form stars across the disk of the spiral galaxy M51. We break the PAWS survey into 370pc and 1.1kpc resolution elements, and within ...
-
(Universidad de Chile, 2016)La observación de emisión Lyman alpha (Lyα) proveniente de galaxias es una técnica ampliamente utilizada para el estudio del universo a alto redshift (e.g. Shapley et al. 2003, Ouchi et al. 2008, Stark et al. 2010, Blanc ...
-
(The American Astronomical Society, 2016)In this work, we show how the stellar mass (M-*) of galaxies affects the 3 < z < 4.6 Ly alpha equivalent width (EW) distribution. To this end, we design a sample of 629 galaxies in the M-* range 7.6 < logM(*)/M-circle dot ...
-
(IOP PUBLISHING LTD., 2016)We compare the physical and morphological properties of z similar to 2 Ly alpha emitting galaxies (LAEs) identified in the HETDEX Pilot Survey and narrow band studies with those of z similar to 2 optical emission line ...
-
(The American Astronomical Society, 2015-01-10)We present a new method for inferring the metallicity (Z) and ionization parameter (q) of H ii regions and star-forming galaxies using strong nebular emission lines (SELs). We use Bayesian inference to derive the joint and ...
-
(Institute of Physics, 2017)We revisit the evolution of the mass–metallicity relation of low- and high-redshift galaxies by using a sample oflocal analogs of high-redshift galaxies. These analogs share the same location of the UV-selected ...
-
(IOP Publishing, 2017)We explore the use of mm-wave emission line ratios to trace molecular gas density when observations integrate over a wide range of volume densities within a single telescope beam. For observations targeting external galaxies, ...
-
(UNIV CHICAGO PRESS, 2008-07-10)We present K-band imaging of two similar to 30' x 30' fields covered by the Multiwavelength Survey by Yale-Chile (MUSYC) Wide NIR Survey. The SDSS 1030+05 and Cast 1255 fields were imaged with the Infrared Side Port Imager ...
-
(The American Astronomical Society, 2015-01-01)We present an overview of a new integral field spectroscopic survey called MaNGA (Mapping Nearby Galaxies at Apache Point Observatory), one of three core programs in the fourth-generation Sloan Digital Sky Survey (SDSS-IV) ...
-
(Royal Astronomical Society, 2015)MaNGA (Mapping Nearby Galaxies at Apache Point Observatory) is a 6-yr Sloan Digital Sky Survey (SDSS-IV) survey that will obtain spatially resolved spectroscopy from 3600 to 10 300 Å for a representative sample of over ...
-
(UNIV CHICAGO PRESS, 2006-05-01)We selected 40 candidate Ly alpha-emitting galaxies ( LAEs) at z similar or equal to 3.1 with observed-frame equivalent widths greater than 150 and inferred emission-line fluxes above 2.5 x 10(-17) ergs cm(-2) s(-1) from ...

(2006-05-01)We selected 40 candidate Lya-emitting galaxies (LAEs) at z 3.1 with observed-frame equivalent widths greater than 150 and inferred emission-line fluxes above 2.5#10 17 ergs cm 2 s 1 from deep narrowband and °A broadband ...

(Universidad de Chile, 2018)En esta tesis estudiamos efectos relativistas en la estructura a gran escala del universo en $\Lambda$CDM y modelos de energía oscura. El término observado de sobredensidad de materia es derivado en el regimen lineal, donde ...
-
(IOP Publishing, 2016)Mapping Nearby Galaxies at Apache Point Observatory (MaNGA), one of three core programs in the Sloan Digital Sky Survey-IV, is an integral-field spectroscopic survey of roughly 10,000 nearby galaxies. It employs dithered ...

(Universidad de Chile, 2022)Para probar las teorías de formación y evolución de galaxias, es muy importante caracterizar en gran escala el gas que las circunda y poder acotar sus propiedades. Los sistemas de absorción de Mg II generalmente son ...
