Upper Limits on Radio Emission from the K2-18 System

Kelvin Wandia, Chenoa Tremblay, Michael A. Garrett +11

Stellar and planetary magnetic fields play a crucial role in the habitability of a planet and the integrity of its atmosphere. The recently claimed detection of biosignatures, meth…

Precise Measurements of Self-absorbed Rising Reverse Shock Emission from Gamma-ray Burst 221009A

Joe S. Bright, Lauren Rhodes, Wael Farah +18

The deaths of massive stars are sometimes accompanied by the launch of highly relativistic and collimated jets. If the jet is pointed towards Earth, we observe a "prompt" gamma-ray…

A Catalog of Filaments in the Central Molecular Zone

Richard G. Arendt, F. Yusef-Zadeh, I. Heywood

We present a catalog of 1.28 GHz radio filaments observed by MeerKAT over the innermost 200 pc of the Galaxy (roughly ), which includes the central molecular zone (CMZ).…

MIGHTEE: A first look at MIGHTEE quasars

Sarah V. White, Ivan Delvecchio, Nathan Adams +6

In this work we study a robust, -band complete, spectroscopically-confirmed sample of 104 unobscured (Type-1) quasars within the COSMOS and XMM-LSS fields of the MeerKAT Inter…

The Accretion-Ejection Connection in the Black Hole X-ray Binary MAXI J1820070

Joe S. Bright, Rob Fender, David M. Russell +12

The black hole X-ray binary MAXI J1820070 began its first recorded outburst in March 2018, and remained an active radio, X-ray, and optical source for over four years. Due to th…

A spatially-resolved spectral analysis of giant radio galaxies with MeerKAT

K. K. L. Charlton, J. Delhaize, K. Thorat +13

In this study we report spatially resolved, wideband spectral properties of three giant radio galaxies (GRGs) in the COSMOS field: MGTC J095959.63+024608.6 , MGTC J100016.84+015133…
