Lensing time delays as a substructure constraint: a case study with the cluster SDSS~J1004+4112
Irshad Mohammed, Prasenjit Saha, Jori Liesenborgs
Gravitational lensing time delays are well known to depend on cosmological parameters, but they also depend on the details of the mass distribution of the lens. It is usual to mode…
Baryonic effects on weak-lensing two-point statistics and its cosmological implications
Irshad Mohammed, Davide Martizzi, Romain Teyssier +1
We develop an extension of \textit{the Halo Model} that describes analytically the corrections to the matter power spectrum due to the physics of baryons. We extend these correctio…
Analytic model for the matter power spectrum, its covariance matrix, and baryonic effects
Irshad Mohammed, Uros Seljak
We develop a model for the matter power spectrum as the sum of Zeldovich approximation and even powers of , i.e., , compensated at low . With ter…
Constraining galaxy cluster temperatures and redshifts with eROSITA survey data
Katharina Borm, Thomas H. Reiprich, Irshad Mohammed +1
The nature of dark energy is imprinted in the large-scale structure of the Universe and thus in the mass and redshift distribution of galaxy clusters. The upcoming eROSITA mission…
Mass-Galaxy offsets in Abell 3827, 2218 and 1689: intrinsic properties or line-of-sight substructures?
Irshad Mohammed, Jori Liesenborgs, Prasenjit Saha +1
We have made mass maps of three strong-lensing clusters, Abell 3827, Abell 2218 and Abell 1689, in order to test for mass-light offsets. The technique used is GRALE, which enables…
