FRB 20201130B, the newest FRB localized by our program, is found to lie at a linear offset of about 3 kpc from a dwarf galaxy (Mr~ -17) at redshift of ~0.2. Deep optical and radio images indicate little stellar population or star-formation at the location, which is unusual compared to other FRBs. The optical observations, affected by weather and visibility, are now completed and are being prepared for publication (Tendulkar et al, in prep).
FRB 20201124A underwent a period of high burst activity that was reported by the CHIME/FRB collaboration. Our VLA observations allowed the precise localization of FRB 20201124A to SDSS J050803.48+260338.0, a star-forming galaxy at a redshift of 0.098. Our deep VLA observations also detected the persistent radio emission from the host galaxy which we showed to be consistent with the expectation from the star formation activity. For more information see, Law et al (2021) and Ravi et al (2021).
In regular observations of the periodic repeater FRB 20180916B, we detected and localized the bursts (Aggarwal, K. et al (2020)). The position was consistent with that measured by the European VLBI network. Our VLA and VLITE observations provided the deepest constraints on the persistent source emission for FRB 20180916B ( Marcote et al 2020).
FRB 20190614D was localized to a pair of faint elliptical galaxies at a photometric redshift between 0.5–0.9. The most-likely redshift is 0.66. With a dispersion measure of 959 pc cm-3, FRB 20190614D is the highest DM FRB, and one of the farthest yet localized. For more details see Law et al (2020).
