Open AccessSearch for non-standard neutrino interactions with 10 years of ANTARES data
Non-standard interactions of neutrinos arising in many theories beyond the Standard Model can significantly alter matter effects in atmospheric neutrino propagation through the Earth. In this paper, a search f...

Multi-scale feedback and feeding in the closest radio galaxy Centaurus A
Supermassive black holes and supernova explosions at the centres of active galaxies power cycles of outflowing and inflowing gas that affect galactic evolution and the overall structure of the Universe1,2. While ...

Open AccessSearch for neutrino counterparts of gravitational-wave events detected by LIGO and Virgo during run O2 with the ANTARES telescope
An offline search for a neutrino counterpart to gravitational-wave (GW) events detected during the second observation run (O2) of Advanced-LIGO and Advanced-Virgo performed with ANTARES data is presented. In a...

VLBI Observations of Low-Redshift Radio Galaxies
Here we will describe briefly some of the VLBI observations we are making of low-redshift, compact radio sources in the southern hemisphere, using the Southern Hemisphere VLBI Experiment (SHEVE) array of teles...

Southern hemisphere VLBI observations of GRO J1655-40
Here we present very long baseline interferometry observations of the Galactic radio and X-ray source GRO J1655-40. These observations show that the radio source which appeared approximately two weeks after th...

The sub-parsec-scale structure and evolution of the jet in centaurus A
We present dual-frequency, co-eval very long baseline interferometry observations of the sub-parsec-scale radio source in Centaurus A which identify the core of the radio source, the origin of the parsec-scale...

VLBI Observations of Southern EGRET Identifications
We present high resolution VLBI images of three southern radio sources: PKS 0208–512, PKS 0521–365 and PKS 0537–441. These sources have been identified as > 100 MeV gamma-ray sources with the Energetic Gamma-R...

A Counterjet in the Nucleus of Centaurus A
Centaurus A (NGC 5128) is the nearest giant radio galaxy. It is a Fanaroff-Riley type 1 (low luminosity) radio source, but the compact radio source in the nucleus is strong enough that VLBI imaging has been po...

Monitoring the Jet in Centaurus a at 0.1 Parsec Resolution
Centaurus A is the closest active extragalactic radio source, at a distance of approximately 3.5 Mpc, and is identified with the peculiar elliptical galaxy NGC 5128. As such it is a very important target for o...
