Ultraviolet Diversity of Type Ia Supernovae [PDF]
, 2016 Ultraviolet (UV) observations of Type Ia supernovae (SNe Ia) probe the
outermost layers of the explosion, and UV spectra of SNe Ia are expected to be
extremely sensitive to differences in progenitor composition and the details of
the explosion.Brown, P., Filippenko, A. V., Foley, Ryan J., Fox, O. D., Hillebrandt, W., Kirshner, R. P., Marion, G. H., Milne, P. A., Pan, Yen-Chen, Parrent, J. T., Pignata, G., Stritzinger, M.

The Astrophysical Journal, 2023 We present multiwavelength time-series spectroscopy of SN 2013aa and SN 2017cbv, two Type Ia supernovae (SNe Ia) on the outskirts of the same host galaxy, NGC 5643. This work utilizes new nebular-phase near-infrared (NIR) spectra obtained by the Carnegie Sahana Kumar, Eric Y. Hsiao, C. Ashall, M. M. Phillips, N. Morrell, P. Hoeflich, C. R. Burns, L. Galbany, E.

, 2004 I discuss the use of Type Ia supernovae (SNe Ia) for cosmological distance
determinations. Low-redshift SNe Ia (z < 0.1) demonstrate that the Hubble
expansion is linear with H_0 = 72 +/- 8 km/s/Mpc, and that the properties of
dust in other galaxies are ...A. Balbi, A. G. Riess, A. G. Riess, A. G. Riess, A. G. Riess, A. G. Riess, A. G. Riess, A. G. Riess, A. G. Riess, A. G. Riess, A. G. Riess, A. G. Riess, A. G. Riess, A.

, 2000 Because calibrated light curves of Type Ia supernovae have become a major
tool to determine the local expansion rate of the Universe and also its
geometrical structure, considerable attention has been given to models of these
