Optical Spectroscopy of Type Ia Supernovae by the Carnegie Supernova Projects I and II
N. Morrell, M. M. Phillips, G. Folatelli +57
We present the second and final release of optical spectroscopy of Type Ia Supernovae (SNe Ia) obtained during the first and second phases of the Carnegie Supernova Project (CSP-I…
SN 2021gno: a Calcium-rich transient with double-peaked light curves
K. Ertini, G. Folatelli, L. Martinez +52
We present extensive ultraviolet (UV) and optical photometric and optical spectroscopic follow-up of supernova (SN)~2021gno by the "Precision Observations of Infant Supernova Explo…
JWST Low-Resolution MIRI Spectral Observations of SN~2021aefx: High-density Burning in a Type Ia Supernova
J. M. DerKacy, C. Ashall, P. Hoeflich +38
We present a JWST/MIRI low-resolution mid-infrared (MIR) spectroscopic observation of the normal Type Ia supernova (SN Ia) SN 2021aefx at +323 days past rest-frame B-band maximum l…
The Carnegie Supernova Project-I. Spectroscopic analysis of stripped-envelope supernovae
S. Holmbo, M. D. Stritzinger, E. Karamehmetoglu +14
An analysis leveraging 170 optical spectra of 35 stripped-envelope (SE) core-collapse supernovae observed by the Carnegie Supernova Project-I and published in a companion paper is…
The Carnegie Supernova Project-I. Optical spectroscopy of stripped-envelope supernovae
M. D. Stritzinger, S. Holmbo, N. Morrell +14
We present 170 optical spectra of 35 low-redshift stripped-envelope core-collapse supernovae observed by the Carnegie Supernova Project-I between 2004 and 2009. The data extend fro…
SN 2021fxy: Mid-Ultraviolet Flux Suppression is a Common Feature of Type Ia Supernovae
J. M. DerKacy, S. Paugh, E. Baron +26
We present ultraviolet (UV) to near-infrared (NIR) observations and analysis of the nearby Type Ia supernova SN 2021fxy. Our observations include UV photometry from Swift/UVOT, UV…
A Speed Bump: SN 2021aefx Shows that Doppler Shift Alone can Explain Early-Excess Blue Flux in Some Type Ia Supernovae
C. Ashall, J. Lu, B. J. Shappee +17
We present early-time photometric and spectroscopic observations of the Type Ia Supernova (SN Ia) 2021aefx. The early time u-band light curve shows an excess flux when compared to…
Carnegie Supernova Project-II: Near-infrared Spectroscopy of Stripped-Envelope Core-Collapse Supernovae
M. Shahbandeh, E. Y. Hsiao, C. Ashall +29
We present 75 near-infrared (NIR; 0.82.5 m) spectra of 34 stripped-envelope core-collapse supernovae (SESNe) obtained by the Carnegie Supernova Project-II (CSP-II), encompass…
A Tale of Two Type Ia Supernovae: The fast-declining siblings SNe 2015bo and 1997cn
W. B. Hoogendam, C. Ashall, L. Galbany +18
We present optical and near-infrared photometric and spectroscopic observations of the fast-declining Type Ia Supernova (SN) 2015bo. SN 2015bo is under-luminous (M = -17.67 $\p…
The Carnegie Supernova Project I: analysis of stripped-envelope supernova light curves
F. Taddia, M. D. Stritzinger, M. Bersten +9
Stripped-envelope (SE) supernovae (SNe) include H-poor (Type IIb), H-free (Type Ib) and He-free (Type Ic) events thought to be associated with the deaths of massive stars. The exac…
