Supernova search at intermediate z. I. Spectroscopic analysis

, 2004
We study 8 supernovae discovered as part of the International Time Programme (ITP) project ``Omega and Lambda from Supernovae and the Physics of Supernova Explosions'' at the European Northern Observatory (ENO). The goal of the project is to increase the

Gamma-Ray Bursts: The Energy Monsters of the Universe

Galaxies
Gamma-Ray Bursts(GRBs) are the most violent and energetic astrophysical phenomena, which I dare call “the Energy Monsters of the Universe”. Indeed, they show an enormous emitted isotropic energy ranging from ∼3 × 1046 erg (GRB 170817A) to ∼1055 erg (GRB ...

Constraining the minimally extended varying speed of light model using time dilations

Frontiers in Astronomy and Space Sciences
The Robertson–Walker (RW) metric, derived from the cosmological principle and Weyl’s postulate, characterizes the ΛCDM cosmological model. Traditionally, in this framework, the assumption of a constant speed of light leads to specific cosmological time ...

Maven: a multimodal foundation model for supernova science

Machine Learning: Science and Technology
A common setting in astronomy is the availability of a small number of high-quality observations, and larger amounts of either lower-quality observations or synthetic data from simplified models.

Constraining the Initial Mass Function via Stellar Transients

Universe
The stellar initial mass function (IMF) represents a fundamental quantity in astrophysics and cosmology describing the mass distribution of stars from low mass all the way up to massive and very massive stars. It is intimately linked to a wide variety of

A Very-High-Energy Gamma-Ray View of the Transient Sky

Universe
The development of the latest generation of Imaging Atmospheric Cherenkov Telescopes (IACTs) over recent decades has led to the discovery of new extreme astrophysical phenomena in the very-high-energy (VHE, E > 100 GeV) gamma-ray regime.
