The Density Contrast of the Shapley Supercluster
Joseph A. Muñoz, Abraham Loeb
We calculate the density contrast of the Shapley Supercluster (SSC) based on the enhanced abundance of X-ray clusters in it using the extended Press-Schechter formalism. We derive…
Light-Cone Distortion of the Clustering and Abundance of Massive Galaxies at High-Redshifts
Joseph A. Muñoz, Abraham Loeb
Observational surveys of galaxies are not trivially related to single-epoch snapshots from computer simulations. Observationally, an increase in the distance along the line-of-sigh…
Verifying the Identity of High-Redshift Massive Galaxies Through the Clustering of Lower Mass Galaxies Around Them
Joseph A. Muñoz, Abraham Loeb
Massive high-redshift galaxies form in over-dense regions where the probability of forming other galaxies is also strongly enhanced. Given an observed flux of a galaxy, the inferre…
Microlensing of a Biconical Broad Line Region
C. Abajas, E. Mediavilla, J. A. Munoz +2
The influence of microlensing in the profiles of the emission lines generated in a biconical geometry is discussed. Microlensing amplification in this anisotropic model is not dire…
Recurrence of the blue wing enhancements in the high ionization lines of SDSS 1004+4112 A
P. Gomez-Alvarez, E. Mediavilla, J. A. Munoz +5
We present integral field spectroscopic observations of the quadruple-lensed QSO SDSS 1004+4112 taken with the fiber system INTEGRAL at the William Herschel Telescope on 2004 Janua…
Microlensing of the Fe K line and the X-ray continuum
L. C. Popovic, P. Jovanovic, E. Mediavilla +4
The observed enhancement of the Fe K line in three gravitationally lensed QSOs (MG J0414+0534, QSO 2237+0305, H1413+117) is interpreted in terms of microlensing, even when equiv…
