The Infrared Supernova Rate
نویسندگان
چکیده
Supernovae (SNe) exploding inside dusty regions could dominate, even by a large amount, the number of core-collapse events in the universe, as most of the starforming activity is hidden by dust. Nevertheless, centuries of optical searches have discovered only very few SNe in dusty regions and no very obscured event. This is clearly a selection effect, and infrared or radio observations are needed to reveal highly obscured SNe. Events detected at these long wavelengths can be used to study the properties of the SNe in dusty galaxies, to obtain a complete estimate of the total SN rate in the local universe, important to calibrate the SN rate at high redshift now under study. In principle the number of events could also be used to derive information on the main energy source (starburst vs. AGN) of the galaxies when they are dominated by a hidden central source, as for the Luminous Infrared Galaxies (LIRGS).

The infrared supernova rate in starburst galaxies
We report the results of our ongoing search for extincted supernovae (SNe) at near-infrared wavelengths. We have monitored at 2.2μm a sample of 46 Luminous Infrared Galaxies and detected 4 SNe. The number of detections is still small but sufficient to provide the first estimate of supernova rate at near-infrared wavelengths. We measure a SN rate of SN r = 7.6±3.8 SNu which is an order of magnit...
متن کاملThe starburst-GRB connection
As starburst galaxies show a star formation rate up to several hundred times larger than the one in a typical galaxy, the expected supernova rate is higher than average. This in turn implies a high rate of long gamma ray bursts (GRBs), which are extreme supernova events. We present a catalog of 127 local starburst galaxies with redshifts of z < 0.03. Using this catalog we investigate the possib...
متن کاملA Search for Fallback Disks in Four Young Supernova Remnants
We report on our search for the optical/infrared counterparts to the central compact objects in four young supernova remnants: Pup A, PKS 1209−52, RCW 103, and Cas A. The X-ray point sources in these supernova remnants are excellent targets for probing the existence of supernova fallback disks, since irradiation of a disk by a central X-ray source should lead to an infrared excess. We used grou...
متن کاملMeasuring Dust Production in the Small Magellanic Cloud Core-collapse Supernova Remnant 1e0102.2−7219
We present mid-infrared spectral mapping observations of the core-collapse supernova remnant 1E 0102.2−7219 in the Small Magellanic Cloud using the InfraRed Spectrograph (IRS) on the Spitzer Space Telescope. The remnant shows emission from fine structure transitions of neon and oxygen as well as continuum emission from dust. Comparison of the mid-IR dust emission with observations at x-ray, rad...
متن کاملSpitzer observations of the N157B supernova remnant and its surroundings
Aims. We study the LMC interstellar medium in the field of the nebula N157B, which contains a supernova remnant, an OB association, ionized gas, and high-density dusty filaments in close proximity. We investigate the relative importance of shock excitation by the SNR and photo-ionization by the OB stars, as well as possible interactions between the supernova remnant and its environment. Methods...
متن کاملThe Star Formation History of the Universe
Strong constraints on the cosmic star formation history (SFH) have recently been established using ultraviolet and far-infrared measurements, refining the results of numerous measurements over the past decade. Taken together, the most recent and robust data indicate a compellingly consistent picture of the SFH out to redshift z ≈ 6, with especially tight constraints for z < 1. There have also b...
