Type I supernovae: an observer’s view [PDF]

open access: yes, 1980
The distinguishing characteristics of Type I supernovae are discussed. Some physical and chemical properties of Type I and Type II supernovae are presented and compared, and processes involved in a supernova explosion are considered.Peer Reviewedhttp ...

Neutrino treatment in multidimensional astrophysical simulations : a new spectral scheme [PDF]

open access: yes, 2014
Neutrinos play a central role in modern physics and astrophysics. Their extremely weak interaction rate with baryons and other leptons makes their detection on the Earth difficult and challenging.

VLBI observations of young Type II supernovae [PDF]

open access: yes, 2020
. We give an overview of circumstellar interaction in young Type II supernovae, as seen through the eyes of verylong-baseline interferometry (VLBI) observations. The resolution attained by such observations ( < ∼ 1 mas) is a powerful tool to probe the

Characterizing The V-Band Light-Curves Of Hydrogen-Rich Type II Supernovae. [PDF]

open access: yes, 2014
Artículo de publicación ISI.We present an analysis of the diversity of V-band light-curves of hydrogen-rich type II supernovae. Analyzing a sample of 116 supernovae, several magnitude measurements are defined, together with decline rates at different ...

Abundance Tomography of Type Ia Supernovae [PDF]

open access: yes, 2004
Many uncertainties about the physics of Type Ia Supernovae have been revealed in the recent past, and numerous pieces are puzzled together to achieve a complete description of the phenomenon of thermonuclear explosions in the sky. However, very important

Peculiar Type II Supernovae from Blue Supergiants [PDF]

open access: yes, 2011
The vast majority of Type II supernovae (SNe) are produced by red supergiants (RSGs), but SN 1987A revealed that blue supergiants (BSGs) can produce members of this class as well, albeit with some peculiar properties.

SN 2021dbg: A Luminous Type IIP–IIL Supernova Exploding from a Massive Star with a Layered Shell

open access: yesThe Astrophysical Journal
We present extensive observations and analysis of supernova (SN) SN 2021dbg, utilizing optical photometry and spectroscopy. For approximately 385 days following the explosion, SN 2021dbg exhibited remarkable luminosity, surpassing most Type II SNe (SNe ...

The ORCA‐TWIN qCMOS Experiment I. Science Case and Commissioning at Calar Alto Observatory

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT We describe a pilot study to explore a new generation of fast and low noise CMOS image sensors for time domain astronomy, using two remote telescopes with a baseline of 1635 km. The experiment involves direct imaging with novel qCMOS image sensor technology that combines fast readout with sub‐electron readout noise.

Air Pollution Quinones Impair Intestinal Barrier Integrity and Endoplasmic Reticulum in Differentiated Caco‐2 Cells

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Particulate matter (PM) is a major global health threat, linked to millions of deaths annually. Beyond inhalation, PM components reach the gastrointestinal tract through the mucociliary escalator or contaminated food and water. Among PM's organic fraction, redox‐active quinones such as 1,2‐naphthoquinone (NQ) and 9,10‐phenanthrenequinone (PQ ...
