THE EXTREMELY LUMINOUS SUPERNOVA 2006gy AT LATE PHASE: DETECTION OF OPTICAL EMISSION FROM SUPERNOVA
Supernova (SN) 2006gy is an extremely luminous Type IIn SN characterized by the bright peak magnitude MR ∼ −22 mag and its long duration. The mechanism giving rise to its huge luminosity is still unclear. We performed optical spectroscopy and photometry of SN 2006gy at late time, ∼ 400 days after the explosion, with the Subaru/FOCAS in a good seeing condition. We carefully extracted the SN comp...
متن کاملOptical detection of the radio supernova SN 2000 ft in the circumnuclear region of the luminous infrared galaxy NGC 7469 ⋆
Context. (Ultra)Luminous Infrared Galaxies (ULIRGs) produce massive stars in large quantities in their central starburst regions. The expected rate of supernova explosions is, on average, about one per year. Detection of these supernovae in the expected numbers has proven elusive so far. Aims. Illustrate the general benefits and limitations of supernova searches in (U)LIRGs in the optical using...
متن کاملA runaway collision in a young star cluster as the origin of the brightest supernova.
Supernova SN 2006gy in the galaxy NGC 1260 is the most luminous recorded. Its progenitor might have been a very massive (>100 Mo, where is the mass of the Sun) star, but that interpretation is incompatible with hydrogen in the spectrum of the supernova; stars >40 Moare believed to have shed their hydrogen envelopes several hundred thousand years before the explosion. Alternatively, the progenit...
متن کاملSN 1996cr: Confirmation of a Luminous Type IIn Supernova in the Circinus Galaxy
We have recently confirmed SN 1996cr as a late-time type IIn supernova (SN) via VLT spectroscopy and isolated its explosion date to ∼1 yr using archival optical imaging. We briefly touch upon here the wealth of optical, X-ray, and radio archival observations available for this enigmatic source. Due to its relative proximity (3.8±0.6 Mpc), SN 1996cr ranks among the brightest X-ray and radio SNe ...
متن کاملLuminous Optical Transient in the Nearby Galaxy Ngc 300 1
A luminous optical transient (OT) that appeared in NGC 300 in early 2008 had a maximum brightness, MV ≃ −13, intermediate between classical novae and supernovae. We present ground-based photometric and spectroscopic monitoring and adaptive-optics imaging of the OT, as well as preand post-outburst space-based imaging with HST and Spitzer. The optical spectrum at maximum showed an F-type supergia...
