The study of star formation activity (SF), active-galactic-nuclei (AGN) and their relation with feedback and accretion mechanisms plays a fundamental role to understand how galaxies evolves. Local Luminous and Ultra-Luminous Infrared Galaxies (U/LIRGs) serves as a key point to facilitate such studies. Radio observations can be made with high-angular resolution, are unaffected by dust, allowing to ... More

Low-luminosity Active Galactic Nuclei (LLAGN) represent a unique class of AGN in the local universe. Extensive studies on them are essential for a comprehensive understanding of jet physics, as past research has been biased towards powerful radio sources. In this talk, we will present our recent VLBI studies of two prominent nearby LLAGN, NGC 4261 and M104 (the Sombrero galaxy). The presentation w ... More

Globular clusters are agglomerations of stars in their advanced stages of evolution, along with the remnants of fully evolved stars, all bound together into a spherical shell by gravitational forces. Due to the dynamic interactions of stars in multiple systems, they host exotic objects e.g., blue stragglers, stellar mass blackholes and fast radio bursts (FRBs). Observations of globular clusters h ... More

AGN are expected to influence galaxy evolution through their fast and powerful outflows which are prominent at radio frequencies, and through ionizing radiation from their accretion disks through processes termed broadly as "AGN feedback". The vast majority of AGN are however radio-quiet and have radio outflows that rarely extend beyond their host galaxies. In this talk, I will present ... More

Water masers associated with AGNs (the `megamasers') constitute a unique way to directly map the molecular gas at (sub-)parsec distance from SMBHs and, hence, to study the physical properties, the structure, and the kinematics of the gas surrounding the central engine. In particular, high angular resolution radio continuum and maser observations have been used to test the alignment of the radio je ... More

Seyfert and Low Ionization Nuclear Emission Line Regions (LINERs) represent radio-quiet (RQ) active galactic nuclei (AGN) commonly observed in spiral galaxies, characterised by prominent emission lines in their optical and ultraviolet spectra. Recent sensitive radio surveys of Seyfert and LINER galaxies have unveiled kiloparsec-scale radio outflows (KSRs) in them (e.g., Gallimore et al. 2006). ... More

Does a broad-line region (BLR) wind in radio-quiet (RQ) active galactic nuclei (AGN) extend to pc scales and produce radio emission associated with the BLR wind? We present the results of EVN (including e-MERLIN) observations at 1.7 and 4.9 GHz of ten (six detected) RQ Palomar-Green (PG) quasars, of which five were selected to have CIV blue excess wing and five without. Together with 13 RQ PG quas ... More
