We present the initial results of our MeerKAT L-band observations of Abell 3376. We achieved higher (5″) angular resolution and better (∼4 μ Jy beam−1) sensitivity compared to the previous observations. Our achieved sensitivity is only a facto

Galaxy clusters are known to harbour magnetic fields. The nature of the intra-cluster magnetic fields remains an unresolved question. Intra-cluster magnetic field can be observed at the density contact discontinuity formed by cool and dense plasma ru

New radio telescope arrays offer unique opportunities for large-scale commensal SETI surveys. Ethernet-based architectures are allowing multiple users to access telescope data simultaneously by means of multicast Ethernet subscriptions. Breakthrough

The new scientific discoveries that will be made by MeerKAT are both exciting and unknown. However, it is precisely the unknown that carries the most risk, and requires scientific software development strategies to help mitigate these risks. Addition

One aspect of the SALT X-ray transient program is the identification of SALT observation time that overlaps with scheduled X-ray satellite observations. This is particularly relevant to the optical study of X-ray transients. Since SALT is a fixed ele

Galaxy clusters are known to harbor magnetic field, however, the extent of the influence of the intra-cluster magnetic field on the cluster member galaxies remains an unresolved question. Intra-cluster magnetic field can be observed as density contac

NGC 6334 I showed evidence of episodic accretion event observed as flares in multiple maser species (water, methanol and hydroxyl) and a brightening of the dust continuum emission in millimetre wavelength. Our multi-epoch water maser observations ove

Following an eruptive accretion event in NGC6334I-MM1, flares in the various maser species, including water masers, were triggered. We report the observed relative proper motion of the highly variable water masers associated with the massive star-for

Using the VLBI Exploration of Radio Astrometry (VERA), we measured the trigonometric parallax of an H2O maser source in a variable star of Mira Cet type, Y Lib, to be 0.855 ± 0.050 mas, corresponding to a distance of 1.17 ± 0.07 kpc. From multi-epo

Rapid technology development has opened up exciting new possibilities in astronomy with larger, more sensitive telescopes that cover large frequency ranges. Telescopes have become bigger and more complex, housing multiple instruments and having wide
