Massive star clusters and clumps in the collisional ring galaxy Arp 147
Z. Randriamanakoto, M. Rakototafika, B. Mongwane +2
We conduct a photometric study of star clusters (or knots) in the collisional ring galaxy (CRG) Arp 147 to trace the star formation history across its empty ring. Using HST F450W,…

The undetectable fraction of core-collapse supernovae in luminous infrared galaxies -- II. GSAOI/GeMS dataset
I. Mäntynen, E. Kankare, S. Mattila +7
Core-collapse supernovae (CCSNe) in luminous infrared galaxies (LIRGs) can have extreme line-of-sight host galaxy dust extinctions, which leads to a large fraction of the events re…

Measurement of the extragalactic background light at 8600Ã using dark cloud shadow and the CaII-triplet lines
Lauri K. Haikala, Kalevi Mattila, Petri Väisänen
We present results of a measurement of the near infrared Extragalactic Background Light using the dark-cloud method. Long-slit spectra covering the opaque core of the intermediate-…
