Abstract

Hyper Suprime-Cam (HSC) is a wide-field imaging camera on the prime focus of the 8.2-m Subaru telescope on the summit of Mauna Kea in Hawaii. A team of scientists from Japan, Taiwan, and Princeton University is using HSC to carry out a 300-night multi-band imaging survey of the high-latitude sky. The survey includes three layers: the Wide layer will cover 1400 deg2 in five broad bands (grizy), with a 5 σ point-source depth of r ≈ 26. The Deep layer covers a total of 26 deg2 in four fields, going roughly a magnitude fainter, while the UltraDeep layer goes almost a magnitude fainter still in two pointings of HSC (a total of 3.5 deg2). Here we describe the instrument, the science goals of the survey, and the survey strategy and data processing. This paper serves as an introduction to a special issue of the Publications of the Astronomical Society of Japan, which includes a large number of technical and scientific papers describing results from the early phases of this survey.

  • Galaxy shredding affects as much as 15% of bright HSC-SSP galaxies, particularly late-type galaxies, causing Kron radius measurements to be significantly underestimated.

    “Galaxy shredding affects as much as 15% of bright HSC-SSP galaxies, particularly late-type galaxies, causing Kron radius measurements to be significantly underestimated.”

    From Detecting galaxy tidal features using self-supervised representation learning (2024) · cites this paper as Aihara et al. 2018

    Section 4 (p. 14) discusses deblending and photometric performance but gives no finding about galaxy shredding. Searches for the 15% figure, late-type galaxies, and Kron radii found no passage addressing the claimed prevalence or measurement bias. (LLM, conf=0.76)

    Experimental — accuracy not yet measured

  • The Kron radii listed in the available HSC-SSP PDR2 catalogues are unreliable and affected by bad segmentation and bright galaxy shredding, where bright (i < 19 mag) galaxies are deblended into multiple objects.

    “WefoundtheKronradii listed in the available HSC-SSP PDR2 catalogues to be unreliable and affected by bad segmentation and "bright galaxy shredding" where bright ( 𝑖 &lt; 19 mag) galaxies are deblended into multiple objects (Aihara et al. 2018).”

    From Detecting galaxy tidal features using self-supervised representation learning (2024) · cites this paper as Aihara et al. 2018

    Section 4 (p. 14) discusses deblending as a general problem in modeling overlapping images, but does not say that bright galaxies are shredded or that Kron radii are unreliable. Section 3.3 (p. 13) discusses a DR1 catalogue, not PDR2. Searches for Kron radii, bright-galaxy shredding, and the i < 19 threshold found no passage addressing those specifics. (LLM, conf=0.76)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
