Off-Axis Energy Variability of AGNs: a New Paradigm for Broad-Line- and Continuum-Emitting Regions
accretion, accretion disks—black hole physics—galaxies: active— galaxies: Seyfert — polarization — quasars: emission lines

The general picture of how thermal AGNs work has become clearer in recent years but major observational puzzles threaten to undermine this picture. These puzzles include AGNs with extremely asymmetric...
Multi-wavelength observations of the young binary system Haro 6-10: The case of misaligned discs
Binary stars - Star Formation - Haro 6-10
<
2011/10/17
Context. We present a multi-wavelength, high-resolution observational survey of the young binary system Haro 6-10 (GV Tau, IRAS 04263+2426), which is harbouring one of the few known infrared companion...

The AKARI All-Sky Catalogues are an important infrared astronomical database for next-generation astronomy that take over the IRAS catalog. We have developed an online service, AKARI Catalogue Archive...
Extinction law in ultraluminous infrared galaxies at z ~ 1
dust, extinction — galaxies: evolution — galaxies: ISM — galaxies: starburst — infrared: galaxies — supernovae: general

2011/10/17
We analyze the multi-wavelength photometric and spectroscopic data of 12 ultraluminous infrared galaxies (ULIRGs) at z ~ 1 and compare them with models of stars and dust in order to study the extincti...

It is only now, with low-frequency radio telescopes, long exposures with high-resolution X-ray satellites and gamma-ray telescopes, that we are beginning to learn about the physics in the periphery of...
Evidence for crust cooling in the transiently accreting 11-Hz X-ray pulsar in the globular cluster Terzan 5
globular clusters: individual (Terzan 5) - X-rays: binaries - stars: neutron -pulsars: individual (CXOGClb J174804.8–244648, IGR J17480–2446)
<

The temporal heating and subsequent cooling of the crusts of transiently accreting neutron stars carries unique information about their structure and a variety of nuclear reaction processes. We report...
A More General Model for the Intrinsic Scatter in Type Ia Supernova Distance Moduli
General Model Intrinsic Scatter Supernova Distance Moduli
<
2011/10/13
We describe a new formalism to fit the parameters $\alpha$ and $\beta$ that are used in the SALT2 model to determine the standard magnitudes of Type Ia supernovae. The new formalism describes the intr...
Emission geometry, radiation pattern, and magnetic topology of the magnetar XTE J1810-197 in its quiescent state
pulsars: general – stars: neutron – X-rays: individual: XTE J1810− 197
<
2011/10/17
The return to the quiescent state of the Anomalous X-ray pulsar XTE J1810-197 following its 2003 outburst represents a unique opportunity to probe the surface emission properties of a magnetar. The qu...

Construction of the cubic-kilometer neutrino detector IceCube at the South Pole has been completed in December 2010. It forms a lattice of 5160 photomultiplier tubes monitoring a gigaton of the deep A...
From the Blazar Sequence to the Blazar Envelope: Revisiting the Relativistic Jet Dichotomy in Radio-loud AGN
Blazar Envelope Revisiting Relativistic Jet Dichotomy Radio-loud AGN
<
2011/10/21
We revisit the concept of a blazar sequence that relates the synchrotron peak frequency ({\nu}peak) in blazars with synchrotron peak luminosity (Lpeak, in {\nu}L{\nu}) using a large sample of radio-lo...
Narrow-line Seyfert 1 galaxies: an amasing class of AGN
Masers – Galaxies: active – Galaxies: nuclei – Galaxies: Seyfert – Radio lines: galaxies
<
2011/10/21
Narrow-line Seyfert 1 (NLS1) galaxies are a class of active galactic nuclei (AGN) that have all the properties of type 1 Seyfert galaxies but show peculiar characteristics, including the narrowest Bal...
