Lessons learned from ongoing coordination between NRAO/GBO and LEO NGSO satellite constellations

Bang D. Nhan, Christopher G. De Pree, Sheldon Wasik +3

With the increased demand for spectrum usage in recent years, particularly with the expansion of NGSO satellite systems for broadband internet and cellular services, radio astronom…

Observations of a Possible Transient Magnetically Arrested Accretion State in a Nearby Quasar: OQ208

Brian Punsly, Cormac Reynolds, Paola Marziani +12

OQ208 is a nearby, partially obscured quasar (z=0.077) that is a young, bright, parsec scale radio source. We assemble archival and new high frequency VLBA and VLA observations and…

Multiwavelength identification of millisecond pulsar candidates in the Galactic bulge

J. Berteaud, F. Calore, M. Clavel +4

The existence of a population of millisecond pulsars in the Galactic bulge is supported, along with other evidence, by the Fermi GeV excess, an anomalous γ-ray emission detected a…

Discovery of two new millisecond pulsars towards the Galactic bulge

J. Berteaud, F. Calore, M. Clavel +13

The mysterious Galactic Center Excess of gamma rays could be explained by a large population of millisecond pulsars hiding in the Galactic bulge, too faint to be detected as indivi…

ODS: A self-reporting system for radio telescopes to coexist with adaptive satellite constellations

Bang D. Nhan, Christopher G. De Pree, Anthony Beasley +14

Low Earth orbit (LEO) satellite constellations bring broadband internet and cellular service to the most remote locations on the planet. Unfortunately, many of these locations also…

Exploring Compact Symmetric Objects with Complex Morphologies

E. E. Sheldahl, G. B. Taylor, S. E. Tremblay +9

Compact symmetric objects (CSOs) are a unique class of jetted active galactic nuclei (AGN) defined by sub-kpc radio emission, showing radio structure on both sides of the central e…
