A super-luminous supernova (SLSN, plural super luminous supernovae or SLSNe) is a type of stellar explosion with a luminosity 10 or more times higher than that of standard supernovae. [1]

極超新星 （英語： superluminous supernova 或 hypernova。 也称为 骇新星），是 超新星 的一種，是年老的 特超巨星 在臨終前的爆發。 這種超新星的威力比起一般的超新星要大得多，剩下的核心會直接塌縮為 黑洞，在黑洞自轉的兩極會以接近 光速 射出高能量 等離子體，充滿著 伽玛射线，成為科學家認為 伽玛射线暴 的可能源頭之一。 透過近幾年的多項觀測結果，人們對伽馬射線暴的瞭解增多。 1990年代，极超新星是指爆炸能量相当于100倍 超新星 爆发。 现在则将所有极 …

SN Ic-SLSN 是Ic型超新星中特别明亮的类型，名称中的SL代表Super Luminous（超亮）。 它们在爆炸的早期阶段，往往表现出独特的氧吸收特征。

2024年7月10日 · We present the most comprehensive catalog to date of Type I Superluminous Supernovae (SLSNe), a class of stripped envelope supernovae (SNe) characterized by exceptionally high luminosities. We have compiled a sample of …

2012年8月15日 · Reviewing the accumulated evidence, we define three broad classes of super-luminous SN events (SLSNe). Hydrogen-rich events (SLSN-II) radiate photons diffusing out from thick hydrogen layers where they have been deposited by strong shocks, and often show signs of interaction with circumstellar material.

2017年3月10日 · A typical supernova shines about as brightly as ten billion Suns at its peak. In the last decade, a new type of supernova was discovered that is ten to one hundred times more luminous than a normal massive stellar collapse supernova, and today over a dozen of these superluminous supernovae (SLSN) have been seen.

2018年12月10日 · We present a sample of 21 hydrogen-free superluminous supernovae (SLSNe-I), and one hydrogen-rich SLSN (SLSN-II) detected during the five-year Dark Energy Survey (DES).

From the accumulated evidence, SLSNe can be classified as radioactively powered (SLSN-R), hydrogen-rich (SLSN-II), and hydrogen-poor (SLSN-I, the most luminous class). The SLSN-II and SLSN-I classes are more common, whereas the SLSN-R class is better understood.

We present the most comprehensive catalogue to date of Type I superluminous supernovae (SLSNe), a class of stripped-envelope supernovae (SNe) characterized by exceptionally high luminosities. We have compiled a sample of 262 SLSNe reported through 2022 December 31.

We present a sample of 21 hydrogen-free superluminous supernovae (SLSNe-I) and one hydrogen-rich SLSN (SLSN-II) detected during the five-year Dark Energy Survey (DES). These SNe, located in the redshift range 0.220 < z < 1.998, represent the largest homogeneously selected sample of SLSN events at high redshift.
