Supernovae Ib/c are likely to be associated to long GRBs, therefore it is important to compare the SN rate in galaxies with the GRB rate. To do that we computed Type Ib/c SN rates in galaxies of different morphological type by assuming different histories of star formation and different supernova Ib/c progenitors. We included some recent suggestions about the dependence of the minimum mass of single Wolf-Rayet (WR) stars upon the stellar metallicity and therefore upon galactic chemical… Expand

A Spectroscopic Study of Type Ibc Supernova Host Galaxies From Untargeted Surveys
We present the first spectroscopic study of the host environments of Type Ibc supernovae (SNe Ibc) discovered exclusively by untargeted SN searches. Past studies of SN Ibc host environments have beenExpand
GRBs have preferred jet opening angles and bulk Lorentz factors
We recently found that Gamma Ray Burst energies and luminosities, in their comoving frame, are remarkably similar. This, coupled with the clustering of energetics once corrected for the collimationExpand
The faster the narrower: characteristic bulk velocities and jet opening angles of gamma-ray bursts
The jet opening angle theta_jet and the bulk Lorentz factor Gamma_0 are crucial parameters for the computation of the energetics of Gamma Ray Bursts (GRBs). From the ~30 GRBs with measured theta_jetExpand
Evidence for the Connection between Prompt and X-ray Afterglow emission of Swift-Detected Gamma-Ray Bursts
When a massive star explodes as a Gamma Ray Burst information about this explosion is retained in the properties of the prompt and afterglow emission. We report on tight relationships between theExpand


The metallicity properties of simulated long-GRB galaxy hosts and the Fundamental Metallicity Relation
We study the implication of the collapsar model for Long Gamma-Ray Bursts (LGRBs) on the metallicity properties of the host galaxies, by combining high-resolution N-body simulations withExpand
The SEDs and host galaxies of the dustiest GRB afterglows
Context. The afterglows and host galaxies of long gamma-ray bursts (GRBs) offer unique opportunities to study star-forming galaxies in the high-z Universe. Until recently, however, the informationExpand
Are Low-luminosity Gamma-Ray Bursts Generated by Relativistic Jets?
Low-luminosity gamma-ray bursts (ll-GRBs) constitute a subclass of GRBs that play a central role in the GRB-supernova connection. While ll-GRBs differ from typical long GRBs (LGRBs) in many aspects,Expand
The Gamma-Ray Burst - Supernova Connection
A preponderance of evidence links long-duration, soft-spectrum gamma-ray bursts (GRBs) with the death of massive stars. The observations of the GRB-supernova (SN) connection present the most directExpand
We present a carefully selected sub-sample of Swift long gamma-ray bursts (GRBs) that is complete in redshift. The sample is constructed by considering only bursts with favorable observing conditionsExpand
Gamma-Ray Bursts as Cosmological Tools
In recent years there has been considerable activity in using gamma-ray bursts as cosmological probes for determining global cosmological parameters complementing results from type Ia supernovae andExpand
Review on the Observed and Physical Properties of core Collapse Supernovae
Core-collapse supernovae prove to comprise the most common general class of exploding star in the Universe and they come in a great variety of flavors. The wide range of luminosities, expansionExpand
The population of GRB hosts
The properties of their hosts provide important clues to the progenitors of different classes of gamma-ray bursts (GRBs). The hosts themselves also constitute a sample of high-redshift star-formingExpand
