CCSNscore: A multi-input deep learning tool for classification of core-collapse supernovae using SED-Machine spectra
Yashvi Sharma, Ashish A. Mahabal, Jesper Sollerman +16
Supernovae (SNe) come in various flavors and are classified into different types based on emission and absorption lines in their spectra. SN candidates are now abundant with the ad…
The Nature of Optical Afterglows Without Gamma-ray Bursts: Identification of AT2023lcr and Multiwavelength Modeling
Maggie L. Li, Anna Y. Q. Ho, Geoffrey Ryan +29
In the past few years, the improved sensitivity and cadence of wide-field optical surveys have enabled the discovery of several afterglows without associated detected gamma-ray bur…
How accurate are transient spectral classification tools? -- A study using 4,646 SEDMachine spectra
Young-Lo Kim, Isobel Hook, Andrew Milligan +13
Accurate classification of transients obtained from spectroscopic data are important to understand their nature and discover new classes of astronomical objects. For supernovae (SN…
The Palomar twilight survey of 'Ayló'chaxnim, Atiras, and comets
B. T. Bolin, F. J. Masci, M. W. Coughlin +29
Near-sun sky twilight observations allow for the detection of asteroid interior to the orbit of Venus (Aylos), the Earth (Atiras), and comets. We present the results of observation…
A cosmic formation site of silicon and sulphur revealed by a new type of supernova explosion
Steve Schulze, Avishay Gal-Yam, Luc Dessart +47
The cores of stars are the cosmic furnaces where light elements are fused into heavier nuclei. The fusion of hydrogen to helium initially powers all stars. The ashes of the fusion…
ZTF SN Ia DR2: Overview
Mickael Rigault, Mathew Smith, Ariel Goobar +53
We present the first homogeneous release of several thousand Type Ia supernovae (SNe Ia), all having spectroscopic classification, and spectroscopic redshifts for half the sample.…
Optical and Radio Analysis of Systematically Classified Broad-lined Type Ic Supernovae from the Zwicky Transient Facility
Gokul P. Srinivasaragavan, Sheng Yang, Shreya Anand +35
We study a magnitude-limited sample of 36 Broad-lined Type Ic Supernovae (SNe Ic-BL) from the Zwicky Transient Facility Bright Transient Survey (detected between March 2018 and Aug…
ZTF SN Ia DR2: The secondary maximum in Type Ia supernovae
M. Deckers, K. Maguire, L. Shingles +24
Type Ia supernova (SN Ia) light curves have a secondary maximum that exists in the , , and near-infrared filters. The secondary maximum is relatively weak in the band, bu…
ZTF SN~Ia DR2: Cosmology-independent constraints on Type Ia supernova standardisation from supernova siblings
S. Dhawan, E. Mortsell, J. Johansson +18
Understanding Type Ia supernovae (SNe~Ia) and the empirical standardisation relations that make them excellent distance indicators is vital to improving cosmological constraints. S…
ZTF SN Ia DR2: Study of Type Ia Supernova lightcurve fits
M. Rigault, M. Smith, N. Regnault +34
Type Ia supernova (SN Ia) cosmology relies on the estimation of lightcurve parameters to derive precision distances that leads to the estimation of cosmological parameters. The emp…
ZTF SN Ia DR2: Colour standardisation of Type Ia Supernovae and its dependence on environment
M. Ginolin, M. Rigault, Y. Copin +37
As type Ia supernova (SN Ia) cosmology transitions from a statistics-dominated to a systematics-dominated era, it is crucial to understand the remaining unexplained uncertainties t…
ZTF SN Ia DR2: Impact of the galaxy cluster environment on the stretch distribution of Type Ia supernovae
F. Ruppin, M. Rigault, M. Ginolin +28
Understanding the impact of the astrophysical environment on Type Ia supernova (SN Ia) properties is crucial to minimize systematic uncertainties in cosmological analyses based on…
