Title: Core-collapse supernovae and their progenitors

Abstract: 
In the recent years we studied a number of core-collapse supernovae (SNe) 
from different surveys. We focused on stripped-envelope SNe (Type Ib/c and IIb), circumstellar-interacting 
SNe (Type IIn, Ibn, Ia-CSM) and peculiar Type II SNe (1987A-like), 
from the intermediate Palomar Transient Factory, from the Carnegie Supernovae Project 
and from the Sloan Digital Sky Survey. We investigated single events, large SN samples, 
and the host galaxies of specific SN groups, aiming to determine the nature of the SN progenitor stars. 
Here we review our main results, in particular those concerning the debate between single
and binary progenitor stars of Type Ib/c, the multi-channel progenitor scenario for SNe IIn and
the variety of 1987A-like progenitor-star radii. We also review the open questions concerning the
SN type <-> progenitor-star map and we discuss how we can address them using 
the new Zwicky Transient Facily survey.
