EVLA imaging of methanimine and hydrogen cyanide in Arp 220
… the nearest Ultraluminous Infrared Galaxy, Arp 220, taken with the Expanded Very Large Array (EVLA) in A configuration. The 5289.8 MHz \meth\ line was detected in emission toward the western nucleus, but not toward the eastern nucleus. The 6731.9 MHz HCN line was detected in absorption …

The Active Phases of a Galaxy in the JWST and Euclid Era: From Radio Jets and Multiphase Outflows to Mergers
… two Ultra Luminous InfraRed Galaxies (ULIRGs), Arp 220 and Mrk231, observed with JWST/NIRSpec. We spatially resolved the ionized and hot molecular gas in the nuclear region and identified multiple high-velocity multiphase outflows originating from both nuclei of Arp220. Combined NIRSpec and ALMA …

Supernovae as gamma ray emitters from the MeV to the TeV
… galaxy and the ultraluminous infrared galaxy Arp 220 exceed our pionic upper-limit; possible explanations are discussed. (2) In our own Galaxy, any supernova explosion would be a spectacular ""once in lifetime"" event. Tragically, a Galactic Type Ia supernova (SNIa) could go entirely unnoticed …
