Getting to Know the Cataclysmic Variable Beneath the Nova Eruption

The eruption of a (classical) nova is widely accepted to be a recurrent
event in the lifetime of a cataclysmic binary star. In-between eruptions
the system should therefore behave as a ``normal'' cataclysmic variable
(CV), i.e. according to its characteristic properties like the
mass-transfer rate or the strength of the magnetic field of the white
dwarf. How important are these characteristics for the nova eruption
itself, i.e. which type of systems preferably undergo a nova eruption?
This question could in principle be addressed by comparing the post-nova
systems with the general CV…


Far-infrared-detected Lyman-break galaxies at z ~ 3. Dust attenuation and dust correction factors at high redshift

Lyman-break galaxies (LBGs) represent one of the kinds of star-forming
galaxies that are found in the high-redshift universe. The detection of
LBGs in the far-infrared (FIR) domain can provide very important clues
on their dust attenuation and total star-formation rate (SFR), allowing
a more detailed study than has been performed so far. In this work we
explore the FIR emission of a sample of 16 LBGs at z ~ 3 in the
GOODS-North and GOODS-South fields that are individually detected in
PACS-100 μm or PACS-160 μm. These detections demonstrate the
possibility of measuring the dust emission of…


Lyman break and UV-selected galaxies at z ~ 1: II. PACS-100um/160um FIR detections

We report the PACS-100um/160um detections of a sample of 42
GALEX-selected and FIR-detected Lyman break galaxies (LBGs) at z ~ 1
located in the COSMOS field and analyze their ultra-violet (UV) to
far-infrared (FIR) properties. The detection of these LBGs in the FIR
indicates that they have a dust content high enough so that its emission
can be directly detected. According to a spectral energy distribution
(SED) fitting with stellar population templates to their UV-to-near-IR
observed photometry, PACS-detected LBGs tend to be bigger, more massive,
dustier, redder in the UV continuum, and…
