Probing the nature of dark matter by forward modeling flux ratios in strong gravitational lenses
Daniel Gilman, Simon Birrer, Tommaso Treu +2
The free streaming length of dark matter particles determines the abundance of structure on sub-galactic scales. We present a statistical technique, amendable to any parameterizati…
AGN photoionization of gas in companion galaxies as a probe of AGN radiation in time and direction
William C. Keel, Vardha N. Bennert, Anna Pancoast +9
We consider AGN photoionization of gas in companion galaxies (cross-ionization) as a way to sample the intensity of AGN radiation in both direction and time, independent of the gas…
Through a Smoother Lens: An expected absence of LCDM substructure detections from hydrodynamic and dark matter only simulations
Andrew S. Graus, James S. Bullock, Michael Boylan-Kolchin +1
A fundamental prediction of the cold dark matter cosmology is the existence of a large number of dark subhalos around galaxies, most of which should be entirely devoid of stars. Co…
Probing dark matter substructure in the gravitational lens HE0435-1223 with the WFC3 grism
A. M. Nierenberg, T. Treu, G. Brammer +7
Strong gravitational lensing provides a powerful test of Cold Dark Matter (CDM) as it enables the detection and mass measurement of low mass haloes even if they do not contain bary…
