Cosmic evolution and metal aversion in super-luminous supernova host galaxies
S. Schulze, T. Krühler, G. Leloudas +21
The SUperluminous Supernova Host galaxIES (SUSHIES) survey aims to provide strong new constraints on the progenitors of superluminous supernovae (SLSNe) by understanding the relati…
A spectroscopic analysis of a sample of narrow-line Seyfert 1 galaxies selected from the Sloan Digital Sky Survey
V. Cracco, S. Ciroi, M. Berton +4
We revisited the spectroscopic characteristics of narrow-line Seyfert 1 galaxies (NLS1s) by analysing a homogeneous sample of 296 NLS1s at redshift between 0.028 and 0.345, extract…
Observational analysis of the well--correlated diffuse bands: 6196 and 6614 Å
J. Krelowski, G. A. Galazutdinov, A. Bondar +1
We confirm, using spectra from seven observatories, that the diffuse bands 6196 and 6614 are very tightly correlated. However, their strength ratio is not constant as well as profi…
Post-maximum near infrared spectra of SN 2014J: A search for interaction signatures
D. J. Sand, E. Y. Hsiao, D. P. K. Banerjee +7
We present near infrared (NIR) spectroscopic and photometric observations of the nearby Type Ia SN 2014J. The seventeen NIR spectra span epochs from +15.3 to +92.5 days after -b…
Type II supernovae as probes of environment metallicity: observations of host HII regions
J. P. Anderson, C. P. Gutierrez, L. Dessart +10
Spectral modelling of SNII atmospheres indicates a clear dependence of metal line strengths on progenitor metallicity. This motivates further work to evaluate the accuracy with whi…
Low Surface Brightness Imaging of the Magellanic System: Imprints of Tidal Interactions between the Clouds in the Stellar Periphery
Gurtina Besla, David Martinez-Delgado, Roeland P. van der Marel +5
We present deep optical images of the Large and Small Magellanic Clouds (LMC and SMC) using a low cost telephoto lens with a wide field of view to explore stellar substructure in t…
