Abstract:
The High Cadence Transient Survey (HiTS) aims to discover and study
transient objects with characteristic timescales between hours and
days, such as pulsating, eclipsing, and exploding stars. This survey
represents a unique laboratory to explore large etendue observations
from cadences of about 0.1 days and test new computational tools for
the analysis of large data. This work follows a fully data science
approach, from the raw data to the analysis and classification of
variable sources. We compile a catalog of ∼15 million object
detections and a catalog of ∼2.5 million light curves classified by
variability. The typical depth of the survey is 24.2, 24.3, 24.1, and
23.8 in the u, g, r, and i bands, respectively. We classified all
point-like nonmoving sources by first extracting features from their
light curves and then applying a random forest classifier. For the
classification, we used a training set constructed using a combination
of cross-matched catalogs, visual inspection, transfer/active
learning, and data augmentation. The classification model consists of
several random forest classifiers organized in a hierarchical scheme.
The classifier accuracy estimated on a test set is approximately 97%.
In the unlabeled data, 3485 sources were classified as variables, of
which 1321 were classified as periodic. Among the periodic classes, we
discovered with high confidence one δ Scuti, 39 eclipsing
binaries, 48 rotational variables, and 90 RR Lyrae, and for the
nonperiodic classes, we discovered one cataclysmic variable, 630 QSOs,
and one supernova candidate.
Description:
The High Cadence Transient Survey (HiTS) was designed to find and
study the early phases of supernova events using the DECam imager at
the 4m Blanco telescope at the Cerro Tololo Inter-American Observatory
(CTIO). In this work, we analyze data from all of the 2013, 2014, and
2015 observational campaigns.
In 2013, we observed 120deg2 in 40 fields during four consecutive
nights, using an exposure time of 173s four times per night with a
cadence of 2hr in the u band.
In 2014, we observed 120deg2 in 40 fields during five consecutive
nights, using an exposure time of 160s four times per night with a
cadence of 2hr in the g band.
In 2015, we observed 150deg2 in 50 fields (with an overlap of 14
fields with 2014) during six consecutive nights, using an exposure
time of 86s five times per night with a cadence of 1.6hr, mostly in
the g band but also including r- and i-band observations.
In 2014 and 2015, we also had imaging follow-up observations after the
main run following an approximately logarithmic spacing in time. For
more details of the survey, see Forster et al. (2016ApJ...832..155F 2016ApJ...832..155F).
In total, we obtained 1980107 detected sources in the u band for 2013
and 5389028 sources in the g band for 2014. For the 2015 observations,
we obtained 5117233 sources in the g band, 5884126 in the r band, and
4572003 in the i band. Due to the overlap of 14 fields between the 2014
and 2015 observation campaigns, 1190008 sources have been cross-matched
using a radius of 0.5" between both catalogs. The number of single-epoch
detections for all three campaigns is about 100 million.
