This article gives an overview of the constitution, physical conditions, and observables of
dust in the interstellar medium of nearby galaxies. We first review the macroscopic, spatial …

A critical review of the very long-standing problem of the diffuse interstellar bands is
presented with emphasis on spectroscopic aspects of observational, modelling and …

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 …

High-dispersion observations of the Na i D λλ5890, 5896 and K i λλ7665, 7699 interstellar
lines, and the diffuse interstellar band at 5780 Å in the spectra of 32 Type Ia supernovae are …

Type Ia supernovae are important cosmological distance indicators. Each of these bright
supernovae supposedly results from the thermonuclear explosion of a white dwarf star that …

Type Ia supernovae are key tools for measuring distances on a cosmic scale. They are
generally thought to be the thermonuclear explosion of an accreting white dwarf in a close …

Abstract Supernova (SN) 2018oh (ASASSN-18bt) is the first spectroscopically confirmed
Type Ia supernova (SN Ia) observed in the Kepler field. The Kepler data revealed an excess …

Life is generally believed to emerge on Earth, to be at least functionally similar to life as we
know it today, and to be much simpler than modern life. Although minimal life is notoriously …

We have studied the afterglow of the gamma-ray burst (GRB) of February 18, 2006. This is a
nearby long GRB, with a very low peak energy, and is therefore classified as an X-ray Flash …

We present imaging and spectroscopy of a hydrogen-poor superluminous supernova
(SLSN) discovered by the intermediate Palomar Transient Factory, iPTF 13ajg. At a redshift …
