The Deepest Radio Study of the Pulsar Wind Nebula G21.5-0.9: Still No Evidence for the Supernova Shell [PDF]
, 2010 We report on sensitive new 1.4-GHz VLA radio observations of the pulsar wind nebula G21.5-0.9, powered by PSR J1833-1034, and its environs. Our observations were targeted at searching for the radio counterpart of the shell-like structure seen surrounding

A Search for Radio Emission at the Bottom of the Main Sequence and Beyond [PDF]
, 1999 We have used the VLA to conduct a deep search for 3.6 cm radio emission from nearby very low mass stars and brown dwarfs. The Gudel-Benz relation is used to predict radio luminosities for some very low mass stars and candidate brown dwarfs with measured ...

Delay and Utilization Analysis of Roadside 5G NR IAB Deployments With Half-Duplex Constraints
IEEE Open Journal of the Communications SocietyThe standardized 3GPP integrated access and backhaul (IAB) technology is expected to provide a cost-efficient densification of 5G New Radio access networks. Relying on multi-hop communications, one of the critical metrics in such a system is latency.
