(Nature Publishing Group, 2018)Every star-forming galaxy has a halo of metal-enriched gas that extends out to at least 100 kiloparsecs(1-3), as revealed by the absorption lines that this gas imprints on the spectra of background quasars(4). However, ...

(Oxford University Press, 2018)Cosmological simulations predict that a significant fraction of the low-z baryon budget resides in large-scale filaments in the form of a diffuse plasma at temperatures T similar to 10(5)-10(7) K. However, direct observation ...

(Oxford Academic, 2018)Cosmological simulations predict that a significant fraction of the low-z baryon budget resides in large-scale filaments in the form of a diffuse plasma at temperatures T ∼ 105 − 107 K. However, direct observation of this ...

(2008)A technique for wavelength calibration promises to revolutionize observational astrophysics, in areas including planet searches and cosmology.

(Oxford Univ Press, 2015)We report long-slit spectroscopic observations of the quasar SDSS J082303.22+052907.6 (z(C IV) similar to 3.1875), whose broad-line region (BLR) is partly eclipsed by a strong damped Lyman alpha (DLA; logN(H I) = 21.7) ...

(Royal Astronomical Society, 2015)We report long-slit spectroscopic observations of the quasar SDSS J082303.22+052907.6 (zC IV ∼ 3.1875), whose broad-line region (BLR) is partly eclipsed by a strong damped Lyman α (DLA; logN(H I) = 21.7) cloud. This ...

(Universidad de Chile, 2013)A la fecha mas de 800 exoplanetas han sido detectados, la mayoría de ellos mediante el método de velocidad radial (VR). De forma tal de obtener VR's precisas, el espectro estelar debe contener miles de lineas de absorción ...

(The American Astronomical Society. All rights reserved. Printed in the U.S.A., 2013-09-01)We present Gemini/GMOS-S multi-object spectroscopy of 31 galaxy cluster candidates at redshifts between 0.2 and 1.0 and centered on QSO sight lines taken from L´opez et al. The targets were selected based on the presence of ...
-
(Oxford University Press, 2020)We present a study of the galaxy environment of nine strong HI + CIV absorption line systems (16.2 < log(N(HI)) < 21.2) spanning a wide range in metallicity at z similar to 4-5, using MUSE integral field and X-Shooter ...
-
(Oxford University Press, 2017-01)The XQ-100 survey provides optical and near-infrared coverage of 36 blindly selected, intervening damped Lyman alpha systems (DLAs) at 2 < z(abs) < 4, simultaneously covering the MgII doublet at lambda lambda 2796, 2803 ...

(Oxford Unv Press, 2020)We present spatially resolved Echelle spectroscopy of an intervening Mg II-Fe II-Mg I absorption-line system detected at z(abs) = 0.73379 towards the giant gravitational arc wPSZ1 G311.65-18.48. The absorbing gas is ...
-
(EDP SCIENCES S.A., 2001-02)We present FWHM = 5 to 8 Angstrom optical spectra of nine previously unknown quasars (QSOs) drawn from the Calan/Tololo Survey. We have chosen this sample based on QSO redshift, z > 3, and the presence of either candidate ...
-
(Oxford University Press, 2020)We present initial results from the Cosmic Ultraviolet Baryon Survey (CUBS). CUBS is designed to map diffuse baryonic structures at redshift z less than or similar to 1 using absorption-line spectroscopy of 15 UV-bright ...
-
(Oxford university press, 2017)We investigate the evolution of the galaxy star formation rate function (SFRF) and cosmic star formation rate density (CSFRD) of z similar to 0-8 galaxies in the Evolution and Assembly of GaLaxies and their Environments ...
-
(Oxford University Press, 2017-05)We present the Lyman α flux power spectrum measurements of the XQ-100 sample of quasar spectra obtained in the context of the European Southern Observatory Large Programme ‘Quasars and their absorption lines: a legacy ...
-
(Universidad de Chile, 2012)In this thesis I present a search for MgII absorption systems in the resolved spectra of 10 high redshifts gravitationally lensed quasars. The goal of the thesis is to study the spatial structure of MgII systems. The quasars ...
-
(EDP Sciences, 2015)We present a detailed analysis of three extremely strong, intervening damped Lyman-α systems (ESDLAs, with log N(H i) ≥ 21.7) observed towards quasars with the Ultraviolet and Visual Echelle Spectrograph on the Very Large ...
