Uncertainties in the production of p nuclides in thermonuclear supernovae determined by Monte Carlo variations
(2018-03-01)
Thermonuclear supernovae originating from the explosion of a white dwarf accreting mass from a companion star have been suggested as a site for the production of p nuclides. Such nuclei are produced during the explosion, ...
Faceting for direction-dependent spectral deconvolution
(2018-03-01)
The new generation of radio interferometers is characterized by high sensitivity, wide fields of view and large fractional bandwidth. To synthesize the deepest images enabled by the high dynamic range of these instruments ...
Massive outflows associated with ATLASGAL clumps
(2018-03-01)
We have undertaken the largest survey for outflows within the Galactic plane using simultaneously observed 13COand C18O data. Out of a total of 919 ATLASGAL clumps, 325 have data suitable to identify outflows, and 225(69% ...
Triggering Active Galactic Nuclei in galaxy clusters
(2018-03-01)
We model the triggering of active galactic nuclei (AGN) in galaxy clusters using the semianalytic galaxy formation model SAGE. We prescribe triggering methods based on the ram pressure galaxies experience as they move ...
RAiSE III : 3C radio AGN energetics and composition
(2018-03-01)
Kinetic jet power estimates based exclusively on observed monochromatic radio luminosities are highly uncertain due to confounding variables and a lack of knowledge about some aspects of the physics of active galactic ...
VIRAC: The VVV Infrared Astrometric Catalogue
(2018-02-21)
We present VIRAC version 1, a near-infrared proper motion and parallax catalogue of the VISTA Variables in the Via Lactea (VVV) survey for 312 587 642 unique sources averaged across all overlapping pawprint and tile images ...
NGC 5626: a massive fast rotator with a twist
(2018-02-11)
We present a kinematic analysis of the dust-lane elliptical NGC 5626 based on MUSE observations. These data allow us to robustly classify this galaxy as a fast rotator and to infer a virial mass of 10 11.7M⊙, making it one ...
Role of Core-collapse Supernovae in Explaining Solar System Abundances of p Nuclides
(2018-02-07)
The production of the heavy stable proton-rich isotopes between 74Se and 196Hg - the p nuclides - is due to the contribution from different nucleosynthesis processes, activated in different types of stars. Whereas these ...
The Ultra-Fast Outflow of the Quasar PG 1211+143 as Viewed by Time-Averaged Chandra Grating Spectroscopy
(2018-02-02)
We present a detailed X-ray spectral study of the quasar PG 1211+143 based on Chandra High Energy Transmission Grating Spectrometer (HETGS) observations collected in a multi-wavelength campaign with UV data using the Hubble ...
Discovery of an Ultraviolet Counterpart to an Ultra-Fast X-ray Outflow in the Quasar PG1211+143
(2018-02-02)
We observed the quasar PG 1211+143 using the Cosmic Origins Spectrograph on the Hubble Space Telescope in 2015 April as part of a joint campaign with the Chandra X-ray Observatory and the Jansky Very Large Array. Our ...
