An attempt to measure the time delays of three gravitational lenses
… of gravitational lens monitoring using the Very Large Array (VLA) at 8.5 GHz. The campaign monitored five gravitational lenses, GL1608, GL1830, GL1632, GL1838, and GL2004 from 24 January 2002 until 18 September 2002, and from 21 May 2003 until 29 January 2004. In addition to gravitational …

Characterization of Radio Emission from Young Stellar Objects
The discovery and characterization of planetary systems have been a prime focus in the field of astronomy for the past few decades. However, in spite of such collective interest and efforts, there still remain many under-explored paths, such as in the realm of star and planet formation. …

Characterizing sub-mm observations of protoplanetary disks at super-resolution scales
… with instruments such as the Atacama Large Millimeter Array (ALMA) and the Karl G. Jansky Very Large Array (VLA) is markedly advancing the protoplanetary disk field. By further improving our methods to reconstruct high fidelity (in terms of both resolution and sensitivity) images from …

Radio-derived three-dimensional structure of a solar active region
… combined microwave observations from the Very Large Array (VLA) and the Owens Valley Solar Array (OVSA). The VLA observations provide excellent image quality at a few widely spaced frequencies while the OVSA data provide information at many intermediate frequencies to fill in the spectral …

The Active Phases of a Galaxy in the JWST and Euclid Era: From Radio Jets and Multiphase Outflows to Mergers
… Explorer (MUSE) integral field spectroscopy, Very Large Array (VLA) and e-MERLIN radio observations with the goal of studying the interplay between radio jets, outflows, and the properties of the interstellar medium (ISM). We detected extended ionized gas outflows (up to 15 kpc, with …

Multiwavelenght study of cluster mergers and consequences for the radio emission properties of galaxy clusters
… was combined with higher frequency data from Very Large Array (VLA) observations. A re–analysis of the optical and X–ray data available in the public archives was carried out for all sources. Propriety deep XMM–Newton and Chandra observations were used to investigate the merger dynamics in …

Radio observations as a tool to study shock interactions and mass ejections in novae
… radio observations of V445 Pup obtained with the Very Large Array (VLA) spanning 1.5°43.3 GHz, to 2001 January and 2008 March (ª 89 ° 2700 days after eruption). The radio light curve is dominated by synchrotron emission over these seven years, and shows four distinct radio flares. Resolved radio …

Observations of disks around the youngest protostars: Characterizing frequency, dust properties, and magnetic fields at the earliest times
… Through observational work with the CARMA, VLA, and ALMA telescope arrays towards some of the youngest protostars, this dissertation addresses a variety of important and outstanding questions regarding the frequency, dust properties, and role of magnetic fields at the earliest times. How is …
