Tracing neutral hydrogen in UGCA 320: A MHONGOOSE perspective on an edge-on dwarf galaxy in a group environment
Nikki Zabel, D. J. Pisano, Sushma Kurapati +8
We present a detailed analysis of the neutral atomic gas (HI) in the dwarf galaxy UGCA 320, observed with the MeerKAT telescope as part of the MHONGOOSE (MeerKAT HI Observations of…

An independent estimate of H(z) at z = 0.5 from the stellar ages of brightest cluster galaxies
S. Ilani Loubser, Adebusola B. Alabi, Matt Hilton +6
Several cosmological observations (e.g., Cosmic Microwave Background (CMB), Supernovae Type Ia, and local distance ladder measurements such as Cepheids) have been used to measure t…
