An H-alpha survey of the host environments of 77 type IIn supernovae within z<0.02

C. L. Ransome, S. M. Habergham Mawson, M. J. Darnley +2

Type IIn supernovae (SNe\,IIn) are an uncommon and highly heterogeneous class of SN where the SN ejecta interact with pre-existing circumstellar media (CSM). Previous studies have…

Diffuse LINER-type emission from extended disc regions of barred galaxies

S. M. Percival, P. A. James

We present a spectroscopic analysis of the central disc regions of barred spiral galaxies, concentrating on the region that is swept by the bar but not including the bar itself (th…

Galaxy and Mass Assembly (GAMA): Variation in Galaxy Structure Across the Green Valley

Lee S. Kelvin, Malcolm N. Bremer, Steven Phillipps +26

Using a sample of 472 local Universe (z<0.06) galaxies in the stellar mass range 10.25 < log M*/M_sun < 10.75, we explore the variation in galaxy structure as a function of morphol…

Galaxy and Mass Assembly (GAMA): Morphological transformation of galaxies across the green valley

M. N. Bremer, S. Phillipps, L. S. Kelvin +13

We explore constraints on the joint photometric and morphological evolution of typical low redshift galaxies as they move from the blue cloud through the green valley and onto the…

Star formation suppression and bar ages in nearby barred galaxies

P. A. James, S. M. Percival

We present new spectroscopic data for 21 barred spiral galaxies, which we use to explore the effect of bars on disk star formation, and to place constraints on the characteristic l…

SN 2016coi/ASASSN-16fp: An example of residual helium in a type Ic supernova?

S. J. Prentice, C. Ashall, P. A. Mazzali +35

The optical observations of Ic-4 supernova (SN) 2016coi/ASASSN-16fp, from to days after explosion, are presented along with analysis of its physical properties.…
