The Evolution of Active Galactic Nuclei in Warm Dark Matter Cosmology [PDF]
, 2013 Recent measurements of the abundance of AGN with low-luminosities (L_X< 10^44 erg/s in the 2-10 keV energy band) at high redshifts z>4 provide a serious challenge for Cold Dark Matter (CDM) models based on interaction-driven fueling of AGN.

Migrating from static to dynamic survivable WDM networks: the capacity-availability trade-off
Revista Facultad de Ingeniería Universidad de Antioquia, 2012 The benefit of migrating from fault-tolerant static WDM networks to survivable dynamic WDM networks is evaluated in terms of the trade-off between the additional network capacity (number of wavelengths) required to provide fault tolerance capability and

Constraining Warm Dark Matter with high-$z$ supernova lensing
, 2014 We propose a new method to constrain the warm dark matter (WDM) particle mass, $m_\chi$, based on the counts of multiply imaged, distant supernovae (SN) produced by strong lensing by intervening cosmological matter fluctuations.
