Sidestepping the inversion of the weak-lensing covariance matrix with Approximate Bayesian Computation
Martin Kilbinger, Emille E. O. Ishida, Jessi Cisewski-Kehe
Weak gravitational lensing is one of the few direct methods to map the dark-matter distribution on large scales in the Universe, and to estimate cosmological parameters. We study a…
SNAD Transient Miner: Finding Missed Transient Events in ZTF DR4 using k-D trees
P. D. Aleo, K. L. Malanchev, M. V. Pruzhinskaya +7
We report the automatic detection of 11 transients (7 possible supernovae and 4 active galactic nuclei candidates) within the Zwicky Transient Facility fourth data release (ZTF DR4…
Fink: early supernovae Ia classification using active learning
Marco Leoni, Emille E. O. Ishida, Julien Peloton +1
We describe how the Fink broker early supernova Ia classifier optimizes its ML classifications by employing an active learning (AL) strategy. We demonstrate the feasibility of impl…
Probabilistic modeling of asteroid diameters from Gaia DR2 errors
Rafael S. de Souza, Alberto Krone-Martins, Valerio Carruba +5
The Gaia Data Release 2 provides precise astrometry for nearly 1.5 billion sources across the entire sky, including several thousand asteroids. In this work, we provide evidence th…
A high pitch angle structure in the Sagittarius Arm
M. A. Kuhn, R. A. Benjamin, C. Zucker +6
Context: In spiral galaxies, star formation tends to trace features of the spiral pattern, including arms, spurs, feathers, and branches. However, in our own Milky Way, it has been…
