Life after eruption - I. Spectroscopic observations of ten nova candidates

Scritto il 10 Apr 2012 alle 01:39 in Pubblicazioni

We have started a project to investigate the connection of post-novae
with the population of cataclysmic variables. Our first steps in this
concern improving the sample of known post-novae and their properties.
Here we present the recovery and/or confirmation of the old novae MT
Cen, V812 Cen, V655 CrA, IL Nor, V2109 Oph, V909 Sgr, V2572 Sgr, and
V728 Sco. Principal photometric and spectroscopic properties of these
systems are discussed. We find that V909 Sgr is a probable magnetic CV,
and that V728 Sco is a high-inclination system. We furthermore suggest
that the two candidate novae V734…

Physical properties of Lyman-alpha emitters at $z\sim 0.3$ from UV-to-FIR measurements

Scritto il 06 Apr 2012 alle 01:39 in Pubblicazioni

The analysis of the physical properties of low-redshift Ly$\alpha$
emitters (LAEs) can provide clues in the study of their high-redshift
analogues. At $z \sim 0.3$, LAEs are bright enough to be detected over
almost the entire electromagnetic spectrum and it is possible to carry
out a more precise and complete study than at higher redshifts. In this
study, we examine the UV and IR emission, dust attenuation, SFR and
morphology of a sample of 23 GALEX-discovered star-forming (SF) LAEs at
$z \sim 0.3$ with direct UV (GALEX), optical (ACS) and FIR (PACS and
MIPS) data. Using the same UV and IR…
