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…
