The infrared-radio relation in the local universe
K. Tisanić, G. De Zotti, A. Amiri +3
The Square Kilometer Array (SKA) is expected to detect high-redshift galaxies with star formation rates (SFRs) up to two orders of magnitude lower than Herschel surveys and will th…
Void Galaxy Distribution: A Challenge for CDM
Saeed Tavasoli
We extract void catalogs from the Sloan Digital Sky Survey Data Release 16 (SDSS DR16) survey and also from the Millennium simulation. We focus our comparison on distribution of ga…
Dynamical Dark Energy Properties Hidden in the Dark Matter Halos and Voids
Aghileh S Ebrahimi, A. Vafaei Sadr, S. Tavasoli
In this paper, we analysed the halos and voids properties of a GR-based N-body simulation carried out at redshifts z= 0.0 and z= 0.8 as differences between dynamical dark energy mo…
Comparing IMF-sensitive indices of intermediate-mass quiescent galaxies in various environments
Elham Eftekhari, Moein Mosleh, Alexandre Vazdekis +1
Using samples drawn from the Sloan Digital Sky Survey, we study for the first time the relation between large-scale environments (Clusters, Groups and Voids) and the stellar Initia…
Role of environment on nuclear activity
Amirnezam Amiri, Saeed Tavasoli, Gianfranco De Zotti
Motivated by the apparently conflicting results reported in the literature on the effect of environment on nuclear activity, we have carried out a new analysis by comparing the fra…
The number of dwarf satellites of disk galaxies versus their bulge mass in the standard model of cosmology
B. Javanmardi, M. Raouf, H. G. Khosroshahi +3
There is a correlation between bulge mass of the three main galaxies of the Local Group (LG), i.e. M31, Milky Way (MW), and M33, and the number of their dwarf spheroidal galaxies.…
Stellar Mass Profiles of Quiescent Galaxies in Different Environments at
Moein Mosleh, Saeed Tavasoli, Sandro Tacchella
We present the stellar mass profiles of 147 isolated quiescent galaxies in very low-density environments (i.e., void regions) in the local Universe () from the Sloan D…
Peculiar velocity measurement in a clumpy universe
Farhang Habibi, Shant Baghram, Saeed Tavasoli
In this work we address the issue of peculiar velocity measurement in a perturbed Friedmann universe using the deviations from measured luminosity distances of standard candles fro…
Probing the Local Bubble with Diffuse Interstellar Bands. II. The DIB properties in the Northern hemisphere
Amin Farhang, Habib G. Khosroshahi, Atefeh Javadi +9
We present a new high signal to noise ratio spectroscopic survey of the Northern hemisphere to probe the Local Bubble and its surroundings using the Å and Å Diffuse…
Unraveling the nature of Gravity through our clumpy Universe
Shant Baghram, Saeed Tavasoli, Farhang Habibi +2
We propose a new probe to test the nature of gravity at various redshifts through large-scale cosmological observations. We use our void catalog, extracted from the Sloan Digital S…
The Galaxy Population In Voids: Are All Voids The Same?
Saeed Tavasoli, Hadi Rahmani, Habib G. Khosroshahi +2
The influence of under-dense environments on the formation and evolution of galaxies is studied by analysing the photometric properties of ~200 galaxies residing in voids, taken fr…
Ultimate age-dating method for galaxy groups; clues from the Millennium Simulations
Mojtaba Raouf, Habib G. Khosroshahi, Trevor J. Ponman +3
There have been a number of studies dedicated to identification of fossil galaxy groups, arguably groups with a relatively old formation epoch. Most of such studies identify fossil…
The challenge of large and empty voids in the SDSS DR7 redshift survey
Saeed Tavasoli, Kaveh Vasei, Roya Mohayaee
We present catalogues of voids for the SDSS DR7 redshift survey and for Millennium I simulation mock data. We aim to compare the observations with simulations based on a CDM mod…
A statistical study of the luminosity gap in galaxy groups
Saeed Tavasoli, Habib G. Khosroshahi, Ali Koohpaee +2
The luminosity gap between the two brightest members of galaxy groups and clusters is thought to offer a strong test for the models of galaxy formation and evolution. This study fo…
The Spatial Distribution Function of Galaxies at High Redshift
Hadi Rahmani, William C. Saslaw, Saeed Tavasoli
This is the first exploration of the galaxy distribution function at redshifts greater than about 0.1. Redshifts are based on the North and South GOODS Catalogs. In each catalog we…
