SN 2017dio: a type-Ic supernova exploding in a hydrogen-rich circumstellar medium
Hanindyo Kuncarayakti, Keiichi Maeda, Christopher J. Ashall +42
SN 2017dio shows both spectral characteristics of a type-Ic supernova (SN) and signs of a hydrogen-rich circumstellar medium (CSM). Prominent, narrow emission lines of H and He are…
The supermassive black hole coincident with the luminous transient ASASSN-15lh
T. Krühler, M. Fraser, G. Leloudas +11
The progenitors of astronomical transients are linked to a specific stellar population and galactic environment, and observing their host galaxies hence constrains the physical nat…
Constraints on core-collapse supernova progenitors from explosion site integral field spectroscopy
H. Kuncarayakti, J. P. Anderson, L. Galbany +7
Observationally, supernovae (SNe) are divided into subclasses pertaining to their distinct characteristics. This diversity reflects the diversity in the progenitor stars. It is not…
The early detection and follow-up of the highly obscured Type II supernova 2016ija/DLT16am
L. Tartaglia, D. J. Sand, S. Valenti +45
We present our analysis of the Type II supernova DLT16am (SN~2016ija). The object was discovered during the ongoing (DLT40) one day cadence supernova search a…
A kilonova as the electromagnetic counterpart to a gravitational-wave source
S. J. Smartt, T. -W. Chen, A. Jerkstrand +118
Gravitational waves were discovered with the detection of binary black hole mergers and they should also be detectable from lower mass neutron star mergers. These are predicted to…
The shape of oxygen abundance profiles explored with MUSE: evidence for widespread deviations from single gradients
L. Sánchez-Menguiano, S. F. Sánchez, I. Pérez +6
We characterise the oxygen abundance radial distribution of a sample of 102 spiral galaxies observed with VLT/MUSE using the O3N2 calibrator. The high spatial resolution of the dat…
