How peculiar was the recent extended minimum - A hint towards double minima
methods data analysis — Sun helioseismology — Sun
2011/8/24
In this paper, we address the controversy regarding the recent extended solar minimum as seen in helioseismic low- and intermediate-degree mode frequencies: studies from different instruments identify...
Light dark matter in the singlet-extended MSSM
Light dark matter the singlet-extended MSSM
2011/1/13
We discuss the possibility of light dark matter in a general singlet extension of the MSSM. Singlino LSPs with masses of a few GeV can explain the signals reported by the CRESST, CoGeNT and possibly ...
Discovery and follow-up studies of the extended, off-plane, VHE gamma-ray source HESS J1507-622
follow-up studies off-plane VHE gamma-ray source HESS J1507-622
2011/1/10
Context: The detection of gamma-rays in the very-high-energy (VHE) range (100 GeV-100 TeV) offers the possibility of studying the parent population of ultrarelativistic particles found in astrophysica...
Galactic cirrus emission at far-infrared wavelengths affects many extragalactic observations. Separating this emission from that associated with extragalactic objects is both important and difficult. ...
The connection between missing AGB stars and extended horizontal branches
missing AGB stars extended horizontal branches
2011/1/13
Recent surveys confirm early results about a deficiency or even absence of CN-strong stars on the asymptotic giant branch (AGB) of globular clusters (GCs), although with quite large cluster-to-cluster...
The dust formed in extended circumstellar envelopes of long-period variables and Miras has a strong influence on the envelope dynamics. A radiatively driven instability caused by the formation of dust...
Galactic Cepheids with Spitzer: II. Search for Extended Infrared Emission
Cepheids — infrared stars — stars mass loss
2010/11/16
A deep and detailed examination of 29 classical Cepheids with the Spitzer Space Telescope has revealed three stars with strong nearby extended emission detected in multiple bands which appears to be p...

2010/11/10
We present results of high resolution ( 55000) spectral observations of 830 photometrically pre-selected candidate red giants in the magnitude range of V = 9-12. We develop a pipeline for automated d...
On the Nature of the HII Regions in the Extended Ultraviolet Disc of NGC 4625

2010/11/12
Using deep Subaru/FOCAS spectra of 34 Hii regions in both the inner and outer parts of the extended ultraviolet (XUV) disc galaxy NGC 4625 we have measured an abundance gradient out to almost 2.5 time...
Extended atmospheres of AGB stars: modeling and measurement
Extended atmospheres AGB stars modeling measurement
2010/11/12
Encoded in the time- and wavelength dependent properties of pulsating AGB stars are the underlying fundamental parameters of mass, composition and evolutionary state. However, the standard technique o...
Extended Lyman-Alpha Emission around Star-forming Galaxies
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/5
Lyman-alpha (Lya) photons generated from reprocessed ionizing photons in star-forming galaxies, once escaping from the interstellar medium, can encounter resonant scatterings with neutral hydrogen ato...
The LABOCA survey of the Extended Chandra Deep Field South: Two modes of star formation in AGN hosts?
galaxies active galaxies starburst infrared galaxies
2010/3/8
We study the co-existence of star formation and AGN activity in X-ray selected AGN by analyzing stacked 870um submm emission from a deep and wide map of the Extended Chandra Deep Field South, obtained...
Extended Horava gravity and Einstein-aether theory
Extended Horava gravity Einstein-aether
2010/3/19
Einstein-aether theory is general relativity coupled to a dynamical, unit timelike vector. If this vector is restricted in the action to be hypersurface orthogonal, the theory is identical to the IR l...
