The place of the Local Group in the cosmic web
Jaime E. Forero-Romero, Roberto E. Gonzalez
We use the Bolshoi Simulation to find the most probable location of the Local Group (LG) in the cosmic web. Our LG simulacra are pairs of halos with isolation and kinematic propert…
Cosmological constraints from the redshift dependence of the Alcock-Paczynski test: galaxy density gradient field
Xiao-Dong Li, Changbom Park, Jaime E. Forero-Romero +1
We propose a method based on the redshift dependence of the Alcock-Paczynski (AP) test to measure the expansion history of the Universe. It uses the isotropy of the galaxy density…
Characterizing SL2S galaxy groups using the Einstein radius
T. Verdugo, V. Motta, G. Foëx +11
We analyzed the Einstein radius, , in our sample of SL2S galaxy groups, and compared it with (the distance from the arcs to the center of the lens), using three differen…
The impact of gas bulk rotation on the lyman-alpha line
Juan N. Garavito-Camargo, Jaime E. Forero-Romero, Mark Dijkstra
We present results of radiative transfer calculations to measure the impact of gas bulk rotation on the morphology of the Lyman emission line in distant galaxies. We model a ga…
The Local Group in the cosmic web
Jaime E. Forero-Romero, Roberto E. Gonzalez
We explore the characteristics of the cosmic web around Local Group(LG) like pairs using a cosmological simulation in the CDM cosmology. We use the Hessian of the gravitational…
Cosmic web alignments with the shape, angular momentum and peculiar velocities of dark matter haloes
Jaime E. Forero-Romero, Sergio Contreras, Nelson Padilla
We study the alignment of dark matter haloes with the cosmic web characterized by the tidal and velocity shear fields. We focus on the alignment of their shape, angular momentum an…
