S. Taubenberger, S. H. Suyu, S. Bag (TUM/MPA Garching), A. Melo (ESO Garching), S. Schuldt (FINCA/University of Helsinki), R. Cañameras (LAM Marseille), Y. Shu (PMO Nanjing), T.-W. Chen (NCU Taiwan), S. J. Smartt (University of Oxford) report/s a classification of object: SN 2026dph
Type: SN IIRedshift: 0.156
Remarks: A spectrum of SN 2026dph obtained on UT 2026 February 22 with the ESO Very Large Telescope UT1, equipped with the FORS2 spectrograph and grism 300I, shows a blue continuum with a broad H alpha P-Cygni line superimposed, consistent with a young Type II supernova. HII-region emission lines from the host galaxy (He I, H alpha, [S II]) yield a redshift of 0.156, in line with SDSS and DESI spectroscopic redshifts of other galaxies in the field. At that redshift, the absolute magnitude of the supernova is about -17.5. An expansion velocity of 12500 km/s is derived from the H alpha absorption.
The following Classification spectrum was provided:
