The Pan-STARRS1 Surveys
Pan-STARRS1 has carried out a set of distinct synoptic imaging sky surveys including the $3\pi$ Steradian Survey and the Medium Deep Survey in 5 bands ($grizy_{P1}$). The mean 5$\sigma$ point sourceExpand
The death of massive stars – I. Observational constraints on the progenitors of Type II-P supernovae
The progenitors of many type II core-collapse supernovae have now been identified directly on pre-discovery imaging. Here we present an extensive search for the progenitors of type Ibc supernovae inExpand
Progenitors of Core-Collapse Supernovae
Knowledge of the progenitors of core-collapse supernovae is a fundamental component in understanding the explosions. The recent progress in finding such stars is reviewed. The minimum initial massExpand
The Complete Light-curve Sample of Spectroscopically Confirmed SNe Ia from Pan-STARRS1 and Cosmological Constraints from the Combined Pantheon Sample

Euclid Definition Study Report
Euclid is a space-based survey mission from the European Space Agency designed to understand the origin of the Universe's accelerating expansion. It will use cosmological probes to investigate theExpand

Abstract Over the last 15 years, the supernova community has endeavoured to directly identify progenitor stars for core-collapse supernovae discovered in nearby galaxies. These precursors are oftenExpand
The VLT-FLAMES survey of massive stars: surface chemical compositions of B-type stars in the Magellanic Clouds
We present an analysis of high-resolution FLAMES spectra of approximately 50 early B-type stars in three young clusters at different metallicities, NGC 6611 in the Galaxy, N 11 in the LargeExpand
An ultraviolet–optical flare from the tidal disruption of a helium-rich stellar core
TLDR
A luminous ultraviolet–optical flare from the nuclear region of an inactive galaxy at a redshift of 0.1696 is reported and it is determined that the disrupted star was a helium-rich stellar core, modulo a factor dependent on the mass and radius of the star disrupted. Expand
The empirical metallicity dependence of the mass-loss rate of O- and early B-type stars
We present a comprehensive study of the observational dependence of the mass-loss rate in stationary stellar winds of hot massive stars on the metal content of their atmospheres. The metal content ofExpand
A kilonova as the electromagnetic counterpart to a gravitational-wave source
TLDR
Observations and physical modelling of a rapidly fading electromagnetic transient in the galaxy NGC 4993, which is spatially coincident with GW170817, indicate that neutron-star mergers produce gravitational waves and radioactively powered kilonovae, and are a nucleosynthetic source of the r-process elements.
