HI in and behind the Hubble Frontier Field Clusters: A Deep MeerKAT Pilot Search out to

Shilpa Ranchod, Roger Deane, Danail Obreschkow +2

The Hubble Frontier Fields (HFF) are a selection of well-studied galaxy clusters used to probe dense environments and distant gravitationally lensed galaxies. We explore the 21cm n…

The Variability of the Black-Hole Image in M87 at the Dynamical Time Scale

Kaushik Satapathy, Dimitrios Psaltis, Feryal Ozel +235

The black-hole images obtained with the Event Horizon Telescope (EHT) are expected to be variable at the dynamical timescale near their horizons. For the black hole at the center o…

MIGHTEE-HI: Discovery of an HI-rich galaxy group at z = 0.044 with MeerKAT

Shilpa Ranchod, Roger P. Deane, Anastasia A. Ponomareva +13

We present the serendipitous discovery of a galaxy group in the XMM-LSS field with MIGHTEE Early Science observations. Twenty galaxies are detected in HI in this group…
