“…For example, Ryder et al (2004) inferred the action of a binary companion from periodic modulations in the radio light curve of SN 2000ig, which was subsequently confirmed from imaging at Gemini (Ryder et al 2006). This would make SN 2004ip the second case, only after SN 2000ft in NGC 7469, where such radio monitoring has been carried out for a SN in the circumnuclear starburst of a LIRG and will help to better understand the behavior of SNe within dense starburst environments (e.g., Alberdi et al 2006). Furthermore, Mattila et al (2007b) estimated an average SFR of 135 yr for IRAS Ϫ1 M , 18293Ϫ3413 corresponding to a CCSN rate of ∼1.0 SN per year.…”

“…An apparent confirmation of such a theory came from the discovery of the radio-bright SN 2000ft (Colina et al 2001a(Colina et al , 2001b) in a circumnuclear starburst ring (∼600 pc from the nucleus) of its LIRG host NGC 7469 ( Mpc). However, the case of SN 2000ft is outstanding D ≈ 70 because its 6 year long VLA monitoring has shown that the supernova shares essentially the same properties that are common to radio SNe identified as Type II SNe, despite having exploded in the dusty and very dense environment of the circumnuclear region (Alberdi et al 2006). We also note that the optical glow of SN 2000ft has recently been identified in archival HST images taken on 2000 May 13 (Colina et al 2007), consistent with the predicted date of the explosion from the analysis of its radio light curves (Alberdi et al 2006).…”

We report a radio detection of supernova SN 2004ip in the circumnuclear region of the luminous infrared galaxy IRAS 18293Ϫ3413 , using Very Large Array (VLA) observations at 8.4 GHz on 2007 June 11. SN 2004ip had been previously discovered at near-infrared wavelengths using adaptive optics observations, but its nature (core collapse or thermonuclear) could not be definitely established. Our radio detection, about 3 years after the explosion of the supernova, indicates a prominent interaction of the ejecta of SN 2004ip with the circumstellar medium, confirming that the supernova was a core collapse event (probably a Type II) and strongly suggesting that its progenitor was a massive star with a significant mass loss prior to its explosion. SN 2004ip has a 8.4 GHz luminosity of ergs s Hz , about 3 times as bright as SN 2000ft in NGC 7469 at a 27 Ϫ1 Ϫ13.5 # 10 similar age; given its projected distance to the nucleus (∼500 pc), it is one of the closest of all known radio SNe to a galaxy nucleus and one of the brightest radio SNe ever.

“…NGC 7469 is a LIRG with L IR = 5 × 10 11 L , at a distance of 70 Mpc (Alberdi et al 2006). NGC 7469 contains a luminous Seyfert 1 nucleus surrounded by a dusty circumnuclear starburst ring of about 1.6 kpc in diameter (Cutri et al 1984;Wilson et al 1986;Wilson et al 1991;Miles et al 1994;Genzel et al 1995;Malkan et al 1998;Scoville et al 2000).…”

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 the previously detected luminous type II radio supernova SN 2000ft in NGC 7469 as a study case. Methods. Multi-epoch Hubble Space Telescope (HST) optical imaging at different wavelengths and two dimensional PSF fitting algorithms are used to search, and characterize, the optical emission of SN 2000ft. Results. SN 2000ft is detected in two independent Planetary Camera images (F547W and F814W) taken May 13, 2000, about two months before the predicted date of the explosion (July 19, 2000), based on the analysis of its radio light evolution by Alberdi and collaborators. The apparent optical magnitudes and red color of SN 2000ft indicate that it is observed through an extinction of at least A V = 3.0 mag. The extinction corrected lower limit to the absolute visual magnitude (M V ≤ −18.0), identifies SN 2000ft as a luminous supernova in the optical, as other luminous radio supernovae before. SN 2000ft exploded in a region located at only 0. 1 (i.e. 34 ± 3 pc) west of a faint cluster (C24). No parent cluster is identified within the detection limits of the HST short exposures. Conclusions. The unambiguous detection of SN 2000ft in the visual shows that multi-epoch sub-arcsecond (FWHM ∼ 0. 1) optical imaging is also a valid tool that should be explored further to detect supernovae in the dusty (circum)nuclear regions of (U)LIRGs.

“…Of these sources detected in the centres of dustobscured galaxies, a large fraction are never optically classified. It is assumed that many of them are massive core-collapse supernovae; extreme examples of these sources may be the those found in the centre of Arp220 [5,20,21,22,23] or the luminous radio supernovae detected in NGC7469 [24,25] (see Fig 2).…”

I will briefly review the current status of radio observations of nearby supernovae and their remnants. This review will initially address observations of the radio 'light' curves of nearby corecollapse supernovae, followed by a more detailed summary of recent Very Long Baseline Interferometric observations of the expansion of nearby supernovae and their remnants. These later sections will concentrate on a few sources, namely those found in M82, SN1993J, and the recent supernova 2004et. In addition, I will discuss the many radio detections of supernovae found in the highly obscured centres of starburst galaxies, such as M82 and Arp220, where no optical detections are possible.
