Morphological Star-Galaxy Separation
Colin T. Slater, Željko Ivezić, Robert H. Lupton
We discuss the statistical foundations of morphological star-galaxy separation. We show that many of the star-galaxy separation metrics in common use today (e.g. by SDSS or SExtrac…
AXS: A framework for fast astronomical data processing based on Apache Spark
Petar Zečević, Colin T. Slater, Mario Jurić +5
We introduce AXS (Astronomy eXtensions for Spark), a scalable open-source astronomical data analysis framework built on Apache Spark, a widely used industry-standard engine for big…
Fast algorithms for slow moving asteroids: constraints on the distribution of Kuiper Belt Objects
Peter J. Whidden, J. Bryce Kalmbach, Andrew J. Connolly +11
We introduce a new computational technique for searching for faint moving sources in astronomical images. Starting from a maximum likelihood estimate for the probability of the det…
An Overview of the LSST Image Processing Pipelines
James Bosch, Yusra AlSayyad, Robert Armstrong +31
The Large Synoptic Survey Telescope (LSST) is an ambitious astronomical survey with a similarly ambitious Data Management component. Data Management for LSST includes processing on…
The total mass of the Large Magellanic Cloud from its perturbation on the Orphan stream
D. Erkal, V. Belokurov, C. F. P. Laporte +13
In a companion paper by Koposov et al., RR Lyrae from \textit{Gaia} Data Release 2 are used to demonstrate that stars in the Orphan stream have velocity vectors significantly misal…
Piercing the Milky Way: an all-sky view of the Orphan Stream
S. E. Koposov, V. Belokurov, T. S. Li +13
We use astrometry, broad-band photometry and variability information from the Data Release 2 of ESA's Gaia mission (GDR2) to identify members of the Orphan Stream (OS) across the w…
