[O II] as an Effective Indicator of the Dependence Between the Standardised Luminosities of Type Ia Supernovae and the Properties of their Host Galaxies
B. Martin, C. Lidman, D. Brout +3
We have obtained IFU spectra of 75 SN Ia host galaxies from the Foundation Supernova survey to search for correlations between the properties of individual galaxies and SN Hubble r…
Damping Wing-Like Features in the Stacked Ly Forest: Potential Neutral Hydrogen Islands at
Yongda Zhu, George D. Becker, Sarah E. I. Bosman +28
Recent quasar absorption line observations suggest that reionization may end as late as . As a means to search for large neutral hydrogen islands at , we revisi…
The Impact of ionization Morphology and X-ray Heating on the Cosmological 21cm Skew Spectrum
J. H. Cook, S. Balu, B. Greig +4
The cosmological 21cm signal offers a potential probe of the early Universe and the first ionizing sources. Current experiments probe the spatially-dependent variance (Gaussianity)…
Critical magnetic Reynolds number of the turbulent dynamo in collisionless plasmas
Radhika Achikanath Chirakkara, Amit Seta, Christoph Federrath +1
The intracluster medium of galaxy clusters is an extremely hot and diffuse, nearly collisionless plasma, which hosts dynamically important magnetic fields of streng…
JWST's PEARLS: Mothra, a new kaiju star at z=2.091 extremely magnified by MACS0416, and implications for dark matter models
J. M. Diego, Bangzheng Sun, Haojing Yan +28
We report the discovery of Mothra, an extremely magnified monster star, likely a binary system of two supergiant stars, in one of the strongly lensed galaxies behind the galaxy clu…
Galaxy And Mass Assembly (GAMA): The group HI mass as a function of halo mass
Ajay Dev, Simon P. Driver, Martin Meyer +11
We determine the atomic hydrogen (HI) to halo mass relation (HIHM) using Arecibo Legacy Fast ALFA survey HI data at the location of optically selected groups from the Galaxy and Ma…
