TL;DR: In this paper, a new He-rich superluminous supernovae (SLSN-I) was discovered, ZTF19aawfbtg (SN2019hge), which has more than 10 optical spectra at phases from $-41$ to $+103$\,days relative to the peak.
Journal Article
Rates and redshift distributions of high-z supernovae
Tomas Dahlen,Claes Fransson +1 more
TL;DR: In this paper, the authors estimate the number of supernovae, and their distribution in redshift, that should be detectable in different filters with various instruments, including both existing and future telescopes, in particular the NGST.
Journal ArticleDOI
MAPPING HIGH-VELOCITY Hα AND Lyα EMISSION FROM SUPERNOVA 1987A
Richard McCray,Claes Fransson,Josefin Larsson,Kari A. Frank,David N. Burrows,Peter Challis,Robert P. Kirshner,Roger A. Chevalier,Peter M. Garnavich,Kevin Heng,Stephen S. Lawrence,Peter Lundqvist,Nathan Smith,George Sonneborn +13 more
TL;DR: In this paper, the authors present new Hubble Space Telescope images of high-velocity H alpha and Ly alpha emission in the outer debris of SN 1987 A. The Ha images are dominated by emission from hydrogen atoms crossing the reverse shock (RS).
Journal ArticleDOI

TL;DR: In this article, the rest frame luminosity function (LF) of both early-type and late-type galaxies to MB − 17.6 for the cluster Cl1601+42 at z = 0.54.
Journal ArticleDOI
