We report the classifications of astrophysical transients from spectroscopic observations with the Kast spectrograph on the Shane telescope obtained on 2024 September 08 UT. The targets were supplied by ZTF, and identified using the target management platform YSE-PZ (Coulter et al., 2023, PASP, 135, 4501). The classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Phase | Notes
ZTF24abeclwh | AT2024txv | 00:21:47.034 | -24:21:08.91 | 0.050 | Ia | -2d | (1)
ZTF24abeivan | AT2024ueo | 03:20:22.252 | -05:36:22.54 | 0.036 | IIn | pre-peak | (2)
ZTF20acwtqim | AT2024uns | 02:34:48.319 | -07:41:00.83 | 0.022 | Ia | -4d | (3)
Notes:
When the redshift is given to 2 decimal places, it is derived from the SN spectrum. Otherwise, the redshift is determined from the host galaxy.
(1) We measure a Si II 6355 absorption velocity of -14,700 km/s.
(2) We identify several narrow emission lines of H and He. We measure a H-alpha emission FWHM of 1,500 km/s.
(3) We measure a Si II 6355 absorption velocity of -11,800 km/s.
