Comparison of statistical treatments for the equation of state for core-collapse supernovae
(2009) [Artigo de periódico]Neutrinos emitted during the collapse, bounce, and subsequent explosion provide information about supernova dynamics. The neutrino spectra are determined by weak interactions with nuclei and nucleons in the inner regions ... -
A microquasar shot out from its birth place
(2004) [Artigo de periódico]We show that the microquasar LS I +61° 303 is running away from its birth place in a young complex of massive stars. The supernova explosion that formed the compact object shot out the X-ray binary with a linear momentum ... -
Neutrino oscillations and instabilities in degenerate relativistic astrophysical plasmas
(2019) [Artigo de periódico]We set up a proposal to extend significantly recent works on neutrino-plasma interaction, allowing the possibility of deep degenerate and relativistic electrons, which are often present in compact stars such as high-density ... -
OzDES multifibre spectroscopy for the Dark Energy Survey : 3-yr results and first data release
(2017) [Artigo de periódico]We present results for the first three years of OzDES, a six year programme to obtain redshifts for objects in the Dark Energy Survey (DES) supernova fields using the 2dF fibre positioner and AAOmega spectrograph on the ... -
SDSS J124043.01+671034.68 : the partially burned remnant of a low-mass white dwarf that underwent thermonuclear ignition?
(2020) [Artigo de periódico]The white dwarf SDSS J124043.01+671034.68 (SDSS J1240+6710) was previously found to have an oxygen-dominated atmosphere with significant traces of neon, magnesium, and silicon. A possible origin via a violent late thermal ... -
Star formation in grand-design, spiral galaxies : young, massive clusters in the near-infrared
(2012) [Artigo de periódico]Aims. Spiral structure is a prominent feature in many disk galaxies and is often outlined by bright, young objects. We study the distribution of young stellar clusters in grand-design spiral galaxies and thereby determine ... -
The Curious Case of PHL 293B : a long-lived transient in a Metal-poor Blue Compact Dwarf Galaxy
(2020) [Artigo de periódico]We report on small-amplitude optical variability and recent dissipation of the unusually persistent broad emission lines in the blue compact dwarf galaxy PHL 293B. The galaxy's unusual spectral features (P Cygni-like ... -
Three globular cluster candidates in the direction of the bulge shown to be small emission nebulae
(1995) [Artigo de periódico]We carried out spectrophotometry in the range 4000- 7000Å and V, I and Gunn z imaging of the initially thought to be globular cluster candidates in the direction of the Galactic bulge TJ 5 and TJ 23 (Terzan & Ju 1980) and ... -
