The Galactic ASKAP (GASKAP) Survey will map HI and OH throughout a large portion of the Milky Way and Magellanic System. I will present an update on the current status of the survey and the Pilot Phase I HI data, which covered the Small Magellanic Cloud, a region in the Milky Way, and the Galactic Centre. I will also outline our current plans to observe the Large Magellanic Cloud in HI for the...

I will discuss the current status of GOTO and GOTO-related activities on La Palma as we continue to develop the program for joint observations with CTA LST-1. Recently, GRB 201015A was promptly observed with MAGIC and GOTO, showcasing the benefits of joint observations of prompt signatures of optical and VHE gamma-ray transients. I will discuss a program direction that GOTO and CTA LST-1 will...

The Mopra Southern Galactic Plane CO Survey covers more than 200 square degrees of the galactic plane, from l=250 to +11 degrees between -1 < b < 1 degrees in the J = 1-0 line of the three most common CO isotopologues (12CO, 13CO and C18O). I will show preliminary results of our final data release, including position-velocity plots and a catalogue of molecular cloud clumps in C18O, which are...

HESS J1804-216 is one of the brightest yet most mysterious TeV gamma-ray sources discovered so far. Previous arcminute-scale investigations of the interstellar medium (ISM) surrounding this source revealed that HESS J1804-216 is likely powered by a middle-aged supernova remnant (SNR) or pulsar. SNRs are believed to accelerate both cosmic-ray protons and electrons at their shock front. These...

HESS J1825-137 is one of the most powerful and luminous TeV gamma-ray pulsar wind nebulae (PWN). To the south of HESS J1825-137, Fermi -LAT observation revealed a new region of GeV gamma-ray emission. This study presents gas data and spectral energy distribution (SED) modelling towards the GeV emission to understand the underlying particle acceleration. Lying to the north of HESS J1825-137,...

Multi-TeV cosmic rays (CRs) are trapped within the Milky Way by the galactic magnetic field and diffuse through the interstellar medium (ISM) for up to a hundred million years, losing energy via various processes. This leads to a "sea" of high-energy particles around the galactic plane, colloquially known as the TeV CR sea. This sea is poorly understood and presents a challenge for modern day...

The extreme and often varying nature of Active Galactic Nuclei can be investigated by observations of very-high-energy gamma rays. Studying their long-term behaviour and flaring episodes requires the ability to take continuous observations over large spans of time. The Cherenkov Telescope Ring is thus a project to establish a worldwide network of Imaging Air Cherenkov Telescopes (IACT). This...

Data from the Fermi-Large Area Telescope has revealed some strong, unexplained, diffuse, non-thermal emission coming from the Galactic bulge which is prominent in the gamma-ray energy range 1-10 GeV with a peak at ~2 GeV. This extended gamma-ray excess in the Milky Way center has been labeled the Galactic center gamma-ray excess (GCE). The origin of the GCE has been vigorously discussed in the...

Interstellar clouds can act as target material for hadronic cosmic rays; gamma rays subsequently produced through inelastic proton-proton collisions and spatially associated with such clouds can provide a key indicator of energetic particle acceleration. However, even in the case that particle acceleration proceeds up to PeV energies, the system of accelerator and nearby target material must...
