Abstract

We present the Dark Energy Survey (DES) discovery of DES15E2mlf, the most distant superluminous supernova (SLSN) spectroscopically con rmed to date. The light curves and Gemini spectroscopy of DES15E2mlf indicate that it is a Type I superluminous supernova (SLSN-I) at z = 1:861 (a lookback time of 10 Gyr) and peaking at MAB = -22:3 0:1 mag. Given the high redshift, our data probe the rest-frame ultraviolet (1400{3500 A) properties of the SN, nding velocity of the Ciii feature changes by 5600kms^-1 over 14 days around maximum light. We nd the host galaxy of DES15E2mlf has a stellar mass of 3:5+3:6 -2:4 109 M , which is more massive than the typical SLSN-I host galaxy.

Host-galaxy properties of 32 low-redshift superluminous supernovae from the palomar transient factory

Journal Article Perley, D. A. ; Quimby, R. M. ; Yan, L. ; ... - The Astrophysical Journal (Online)

In this paper, we present ultraviolet through near-infrared photometry and spectroscopy of the host galaxies of all superluminous supernovae (SLSNe) discovered by the Palomar Transient Factory prior to 2013 and derive measurements of their luminosities, star formation rates, stellar masses, and gas-phase metallicities. We find that Type I (hydrogen-poor) SLSNe (SLSNe I) are found almost exclusively in low-mass (M_∗ < 2 x 10⁹ M_⊙) and metal-poor (12 + log₁₀[O/H] < 8.4) galaxies. We compare the mass and metallicity distributions of our sample to nearby galaxy catalogs in detail and conclude that the rate of SLSNe I as a fractionmore »« less

DES13S2cmm: The first superluminous supernova from the Dark Energy Survey

Journal Article Papadopoulos, A. ; Plazas, A. A. ; D"Andrea, C. B. ; ... - Monthly Notices of the Royal Astronomical Society

We present DES13S2cmm, the first spectroscopically-confirmed superluminous supernova (SLSN) from the Dark Energy Survey (DES). We briefly discuss the data and search algorithm used to find this event in the first year of DES operations, and outline the spectroscopic data obtained from the European Southern Observatory (ESO) Very Large Telescope to confirm its redshift (z = 0.663 ± 0.001 based on the host-galaxy emission lines) and likely spectral type (type I). Using this redshift, we find M^peak_U = –21.05^+0.10_–0.09 for the peak, rest-frame U-band absolute magnitude, and find DES13S2cmm to be located in a faint, low-metallicity (sub-solar), low stellar-mass hostmore »« less

PS1-10bzj: A FAST, HYDROGEN-POOR SUPERLUMINOUS SUPERNOVA IN A METAL-POOR HOST GALAXY

Journal Article Lunnan, R. ; Chornock, R. ; Berger, E. ; ... - Astrophysical Journal

We present observations and analysis of PS1-10bzj, a superluminous supernova (SLSN) discovered in the Pan-STARRS Medium Deep Survey at a redshift z = 0.650. Spectroscopically, PS1-10bzj is similar to the hydrogen-poor SLSNe 2005ap and SCP 06F6, though with a steeper rise and lower peak luminosity (M{sub bol} {approx_equal} -21.4 mag) than previous events. We construct a bolometric light curve, and show that while PS1-10bzj's energetics were less extreme than previous events, its luminosity still cannot be explained by radioactive nickel decay alone. We explore both a magnetar spin-down and circumstellar interaction scenario and find that either can fit the data.more »« less

The hydrogen-poor superluminous supernova iPTF 13ajg and its host galaxy in absorption and emission

Journal Article Vreeswijk, Paul M. ; Gal-Yam, Avishay ; De Cia, Annalisa ; ... - Astrophysical Journal

We present imaging and spectroscopy of a hydrogen-poor superluminous supernova (SLSN) discovered by the intermediate Palomar Transient Factory, iPTF 13ajg. At a redshift of z = 0.7403, derived from narrow absorption lines, iPTF 13ajg peaked at an absolute magnitude of M {sub u,} {sub AB} = –22.5, one of the most luminous supernovae to date. The observed bolometric peak luminosity of iPTF 13ajg is 3.2 × 10{sup 44} erg s{sup –1}, while the estimated total radiated energy is 1.3 × 10{sup 51} erg. We detect narrow absorption lines of Mg I, Mg II, and Fe II, associated with the coldmore »« less
