Multi-wavelength emission from massive star associations
Results from a new multi-wavelength evolutionary synthesis model including the γ-ray line emission from various radioactive isotopes (26Al, 60Fe) are presented...
Multiple major outbursts from a restless luminous blue variable in NGC 3432
We present new photometric and spectroscopic observations of an unusual luminous blue variable (LBV) in NGC 3432, covering three major outbursts in 2008 October...
Multiwavelength follow-up of a rare IceCube neutrino multiplet
On February 17, 2016, the IceCube real-time neutrino search identified, for the first time, three muon neutrino candidates arriving within 100 s of one another...
Nearby supernova host galaxies from the CALIFA Survey. I. Sample, data analysis, and correlation to star-forming regions
We use optical integral field spectroscopy (IFS) of nearby supernova (SN) host galaxies (0.005 2.4 Gyr, respectively) than the massive SN Ia hosts (0.04%, 2.01%...
Nebular Spectra of the Type Ic Supernovae 1997B and 1997X
New spectra of the Type Ic supernovae 1997B and 1997X at nebular phase are shown. Although one of them, SN 1997X, was studied with some detail around its...
NGC 4526 gas, high velocity clouds, and Galactic halo gas: the interstellar medium towards SN 1994D.
We present spectroscopic observations of supernova 1994D in NGC 4526, an S0_3_ galaxy in the Virgo cluster 15Mpc distant. The datasets consist of the...
We have surveyed Kepler’s supernova remnant in search of the companion star of the explosion. We have gone as deep as 2.6 L ⊙ in all stars within 20% of the...
The Astrophysics Research Institute (ARI) was established at LJMU in 1992. Today the Institute comprises around 70 staff and research students working on topics...
