Galaxy Mergers at z>1 in the HUDF: Evidence for a Peak in the Major Merger Rate of Massive Galaxies
R. E. Ryan, S. H. Cohen, R. A. Windhorst +1
We present a measurement of the galaxy merger fraction and number density from observations in the Hubble Ultra Deep Field for 0.5<z<2.5. We fit the combination of broadband data a…
AGN feedback from Jet-ISM/IGM interactions
V. Antonuccio-Delogu, J. Silk
We study the propagation of relativistic jets originating from AGNs within the Interstellar/Intergalactic Medium of their host galaxies, and use it to build a model for the suppres…
The UV properties of E+A galaxies: constraints on feedback-driven quenching of star formation
S. Kaviraj, L. A. Kirkby, J. Silk +1
We present the first large-scale study of E+A (post-starburst) galaxies that incorporates photometry in the ultraviolet (UV) wavelengths. We find that the starburst that creates th…
Observational biases in Lagrangian reconstructions of cosmic velocity fields
G. Lavaux, R. Mohayaee, S. Colombi +3
Lagrangian reconstruction of large-scale peculiar velocity fields can be strongly affected by observational biases. We develop a thorough analysis of these systematic effects by re…
Sterile neutrinos as subdominant warm dark matter
A. Palazzo, D. Cumberbatch, A. Slosar +1
In light of recent findings which seem to disfavor a scenario with (warm) dark matter entirely constituted of sterile neutrinos produced via the Dodelson-Widrow (DW) mechanism, we…
Cluster abundances and S-Z power spectra: effects of non-Gaussianity and early dark energy
S. Sadeh, Y. Rephaeli, J. Silk
In the standard Lambda CDM cosmological model with a Gaussian primordial density fluctuation field, the relatively low value of the mass variance parameter (sigma_8=0.74{+0.05}{-0.…
