We present a sample of blazar candidates from the Very Large Array Sky Survey (VLASS) catalog, with cross-referencing to optical and infrared data from the Panoramic Survey...

The Planck Catalogue of Compact Sources (PCCS2) is an unbiased census of the millimetre sky at sub-Jansky levels, and thus a valuable resource for studies of galaxy evolution....

We examine the H I gas kinematics of galaxy pairs in two clusters and a group using Australian Square Kilometre Array Pathfinder (ASKAP) WALLABY pilot survey observations. We...

The origin of the radio emission in active galactic nuclei (AGN) is still debated. Multiple physical mechanisms can contribute to the spectrum at these frequencies, including...

Based on the classical unification, blazars, namely BL Lacertae objects (BL Lacs) and flat-spectrum radio quasars (FSRQs), are believed to correspond with radio galaxies when...

We conducted an extensive identification and analysis of various morphological classes and subclasses of radio galaxies using the latest high-resolution data from the second...

The LOFAR Two Meter Sky Survey LoTSS DR2 (:bibcode:2022A&A...659A...1S) obtained radio data from 27% of the northern sky between 120 and 168 MHz in the year 2014 through...

We present high spatial resolution (~= 12 pc) Atacama Large Millimeter/submillimeter Array 12CO(J = 3-2) observations of the nearby lenticular galaxy NGC 4429. We identify 217...

The fundamental plane of black hole activity describes the correlation between radio luminosity (L_R_), X-ray luminosity (L_X_), and black hole mass (M_BH_). It reflects a...

The 'Local Volume HI Survey' (LVHIS) comprises deep HI spectral line and 20-cm radio continuum observations of 82 nearby, gas-rich galaxies, supplemented by multiwavelength...

Cross-identifying complex radio sources with optical or infrared (IR) counterparts in surveys such as the Australia Telescope Large Area Survey (ATLAS) has traditionally been...

We present the first dedicated observations of Interplanetary Scintillation (IPS) with the Murchison Widefield Array. We have developed a synthesis imaging technique, tailored...

We carried out deep H{alpha} narrowband imaging with 10h net integrations towards the young protocluster, USS1558-003 at z=2.53 with the Subaru Telescope. This system is...

We use observations made with the Giant Metrewave Radio Telescope (GMRT) to probe the neutral hydrogen (HI) gas content of field galaxies in the VIMOS VLT Deep Survey (VVDS) 14h...

We present 15 GHz stacked VLBA images of 373 jets associated with active galactic nuclei (AGN) having at least 5 observing epochs within a 20yr time interval 1994-2015 from the...

Powerful radio galaxies exist as either compact or extended sources, with the extended sources traditionally classified by their radio morphologies as Fanaroff-Riley (FR) type I...

The Lockman Hole is a well-studied extragalactic field with extensive multi-band ancillary data covering a wide range in frequency, essential for characterizing the physical and...

We present the results of 325MHz Giant Metrewave Radio Telescope observations of a supercluster field, known to contain five Abell clusters at redshift z~0.2. We achieve a...

We present a deep near-infrared (NIR; J, H, and K_s_ bands) photometric catalogue of sources from the Parkes HI Zone of Avoidance (HIZOA) survey, which forms the basis for an...
