Dwarf galaxies and the cosmic web
(IOP Publishing, 2013-01)
We use a cosmological simulation of the formation of the Local Group of Galaxies to identify a mechanism that enables the removal of baryons from low-mass halos without appealing to feedback or reionization. As the Local ...
Stellar feedback from black-hole high-mass X-ray binaries in galaxy formation models
(Universidad Nacional Autónoma de México. Instituto de Astronomía, 2014)
In recent years, many works have suggested the role of black-hole high-mass X-ray binaries (BH-HMXB) as potential sources of heating and re-ionization in the interstellar and intergalactic medium. Furthermore, because of ...
Equatorial outflows driven by jets in Population III microquasars
(Springer, 2021-01)
Binary systems of Population III can evolve to microquasars when one of the stars collapses into a black hole. When the compact object accretes matter at a rate greater than the Eddington rate, powerful jets and winds ...
The ALPINE-ALMA [CII] survey: Survey strategy, observations, and sample properties of 118 star-forming galaxies at 4<z<6
(European Southern Observatory, 2020)
The ALMA-ALPINE [CII] survey is aimed at characterizing the properties of a sample of normal star-forming galaxies (SFGs). The ALMA Large Program to INvestigate (ALPINE) features 118 galaxies observed in the [CII]-158μm ...
The ALPINE-ALMA [CII] survey: Dust attenuation properties and obscured star formation at z ~ 4:4 - 5:8
(European Southern Observatory, 2020)
We present dust attenuation properties of spectroscopically confirmed star forming galaxies on the main sequence at a redshift of ∼4.4 − 5.8. Our analyses are based on the far infrared continuum observations of 118 galaxies ...
The faint host galaxies of CIV absorbers at z > 5
(Wiley Blackwell Publishing, Inc, 2020-02-18)
We explore the expected galaxy environments of CIV absorbers at z > 5 using the Technicolor Dawn simulations. These simulations reproduce the observed history of reionization, the z ~ 6 galaxy stellar mass function, the ...
Importance of considering helium excited states in He + scattering by an aluminum surface
(American Physical Society, 2014-11)
The He+/Al system is a very interesting projectile-surface combination which was thought initially as an example of a pure Auger neutralization mechanism. Then, because of the measured reionization explained by the antibonding ...
Green Peas in X-Rays
(IOP Publishing, 2019-08)
Green Peas represent a population of compact, highly star-forming dwarf galaxies at redshifts z ∼ 0.2-0.3 that have recently been found to show signatures of ultraviolet ionizing radiation leakage. They are being considered ...
The Hα luminosity function of galaxies AT z ~ 4.5
(Universidad de Chile, 2022)
The Luminosity Function (LF) is one of the most fundamental observables to study galaxies; moreover, choosing a luminosity tracer that strongly correlates with the Star Formation Rate (SFR) allows us to study the evolution ...
Super-luminous type II supernovae powered by magnetars
(EDP Sciences, 2018-05-15)
Magnetar power is believed to be at the origin of numerous super-luminous supernovae (SNe) of Type Ic, arising from compact, hydrogen-deficient, Wolf-Rayet type stars. Here, we investigate the properties that magnetar power ...
