The Cosmic Rate, Luminosity Function and Intrinsic Correlations of Long GRBs

TL;DR: In this paper, the authors presented a catalog of 425 Swift GRBs (147 with redshifts) starting from GRB041220 and calculated durations and spectral parameters for 207 Swift bursts detected by the BAT instrument.
Journal ArticleDOI

Improved standardization of type ii-p supernovae: application to an expanded sample

TL;DR: In this paper, the authors derived a tight Hubble diagram with a dispersion of 10% in distance, using the simple correlation between luminosity and photospheric velocity introduced by Hamuy and Pinto and showed that the descendent method of Nugent et al. can be further simplified and that the correction for dust extinction has low statistical impact.
Journal ArticleDOI

Optimal time-series selection of quasars

TL;DR: In this article, the authors proposed a method for the optimal selection of quasars using time-series observations in a single photometric bandpass. But the method is not suitable for high redshift and in the regime of noisy and sparse data.
Journal ArticleDOI

Construction of a Calibrated Probabilistic Classification Catalog: Application to 50k Variable Sources in the All-Sky Automated Survey

TL;DR: The Machine-learned ASAS Classification Catalog (MACC) as discussed by the authors is a probabilistic classification catalog of variability with machine learning from a multi-epoch photometric survey.
