Supernovae Ia ejecta velocities and host galaxy environments: the role of survey-selection effects
L. V. Barkhudaryan, A. A. Hakobyan, M. H. Gevorgyan +6
The origin of the near-maximum-light Si II 6355 velocity diversity among supernovae Ia (SNe Ia) remains uncertain. Previous studies have suggested that high-velocity (HV) and no…
Calcium versus silicon ejecta velocities and decline rates in supernovae Ia: The role of high-velocity features
A. A. Hakobyan, M. H. Gevorgyan, A. G. Karapetyan +4
Photospheric and high-velocity features (PVFs and HVFs) of Si II 6355 and Ca II IR3 lines in supernova Ia (SN Ia) spectra provide insights into ejecta structure, energetics, and…
The Lyman Alpha Reference Sample. XVI. Global 21cm HI properties of Lyman- emitting galaxies
A. Le Reste, M. J. Hayes, J. M. Cannon +9
The Lyman- (Lya) line of hydrogen is a well-known tracer of galaxies at high-z. However, the connection between Lya observables and galaxy properties has not fully been establis…
Haro 11: The Spatially Resolved Lyman Continuum Sources
Lena Komarova, M. S. Oey, Svea Hernandez +13
As the nearest confirmed Lyman continuum (LyC) emitter, Haro 11 is an exceptional laboratory for studying LyC escape processes crucial to cosmic reionization. Our new HST/COS G130M…
The Lyman Reference Sample XIV: Lyman imaging of 45 low redshift star-forming galaxies and inferences on global emission
Jens Melinder, Göran Östlin, Matthew Hayes +18
We present Ly imaging of 45 low redshift star-forming galaxies observed with the Hubble Space Telescope. The galaxies have been selected to have moderate to high star formation…
The Lyman Alpha Reference Sample XIII: High-Angular Resolution 21cm HI observations of Ly emitting galaxies
A. Le Reste, M. Hayes, J. M. Cannon +8
The Ly emission line is one of the main observables of galaxies at high redshift, but its output depends strongly on the neutral gas distribution and kinematics around the star-…
