PublicaciónMetal-line emission from the warm-hot intergalactic medium - I. Soft X-rays
Emission lines from metals offer one of the most promising ways to detect the elusive warm-hot intergalactic medium (WHIM; 105 < T < 107K), which is thought to...

PublicaciónMetal-line emission from the warm-hot intergalactic medium - II. Ultraviolet
Approximately half the baryons in the local Universe are thought to reside in the warm-hot intergalactic medium (WHIM), i.e. diffuse gas with temperatures in...

PublicaciónMore Evidence for a Population of Intracluster Planetary Nebulae in the Virgo Cluster
We surveyed a 50 arcmin 2 region in the Virgo cluster core to search for intergalactic planetary nebulae and found 11 candidates in the surveyed area. The...

PublicaciónNanodiamond Dust and the Far-Ultraviolet Quasar Break
We explore the possibility that the steepening observed shortward of 1000 Å in the energy distribution of quasars may result from absorption by dust, being...

PublicaciónNarrow band survey for intragroup light in the Leo HI cloud. Constraints on the galaxy background contamination in imaging surveys for intracluster planetary nebulae
We have observed emission line objects located in a 0.26 deg2 field in the M 96 (Leo) group, coincident with the intergalactic HI cloud. The emission line...

PublicaciónOn the Dearth of Ultra-faint Extremely Metal-poor Galaxies
Local extremely metal-poor galaxies (XMPs) are of particular astrophysical interest since they allow us to look into physical processes characteristic of the...
