Detection of the thermal radio continuum emission from the G9.62+0.19-F Hot Core
We present new high resolution and high sensitivity multi-frequency VLA radio continuum observations of the G9.62+0.19-F hot molecular core. We

Modeling the evolution of Sakurai's object
Sakurai's object is a born again AGB star of the very late thermal pulse flavor. In this contribution I will

A Model for Non High Energy Gamma Ray Bursts and Sources of Ultra High Energy Cosmic Rays
As a progenitor of NHE (Non High Energy) GRBs, we propose a (C+O) star and a neutron star (black hole)

Modelling the effects of dust on galactic SEDs from the UV to the millimeter band
We present models of photometric evolution of galaxies in which the effects of a dusty interstellar medium have been included

Formation of the binary pulsars PSR B2303+46 and PSR J1141-6545 - young neutron stars with old white dwarf companions
We have investigated the formation of the binary radio pulsars PSR B2303+46 and PSR J1141-6545 via Monte Carlo simulations of

Two clocks in the PSR J0737--3039 binary system and their implications for the system's origin and evolution
As discussed elsewhere in these proceedings, the double pulsar system is a magnificent laboratory for gravitational physics and for studying

A stellar endgame -- the born-again Sakurai's object
The surface chemical composition of this remarkable star shows that it is hydrogen-deficient, carbon-rich and enriched in the light s-process

Formation of Compact Binaries in Globular Clusters
We report here on two complementary population synthesis studies which relate directly to the formation and evolution of neutron star

Multiwavelength Searches of Unidentified EGRET Sources
3EG J1835+5918 is the brightest of the so-called unidentified EGRET sources at intermediate galactic latitude (l,b)=(89,25). We obtained complete radio,

The Connection among Gamma-ray Burst Host-Galaxies, BL Lacs and Quasars
A possible connection among host-galaxies of gamma-ray bursts, BL Lacs and quasars is analysed. It is believed that the gamma-ray
