Marginalized planet-to-star radius ratio posteriors for low-SNR transiting planets via dimensionality reduction
Oryna Ivashtenko, Barak Zackay
Occurrence rate estimates of small long-period planets rely on the radii of low signal-to-noise ratio transit candidates whose posteriors should be propagated into the population i…
Searching for precessing binary systems with mode-by-mode filtering and marginalization
Zihan Zhou, Digvijay Wadekar, Javier Roulet +8
Nearly all previous binary black hole searches in LIGO--Virgo--KAGRA (LVK) gravitational wave data have assumed that the component spins are aligned with the orbital angular moment…
Sampler-free gravitational wave inference using matrix multiplication
Jonathan Mushkin, Javier Roulet, Barak Zackay +5
Parameter estimation (PE) for compact binary coalescence (CBC) events observed by gravitational wave (GW) laser interferometers is a core task in GW astrophysics. We present a meth…
An Independent Search for Small Long-period Planets in Kepler Data I: Detection Pipeline
Oryna Ivashtenko, Barak Zackay
The unprecedented photometric precision of Kepler mission allows searching for Earth-like planets. However, it remains difficult to distinguish these low signal-to-noise planets fr…
fBLS -- a fast-folding BLS algorithm
Sahar Shahaf, Barak Zackay, Tsevi Mazeh +2
We present fBLS -- a novel fast-folding technique to search for transiting planets, based on the fast-folding algorithm (FFA), which is extensively used in pulsar astronomy. For a…
Origami launcher
Oryna Ivashtenko, Polina Kofman, Oleksiy Golubov +1
The article studies the elastic and locomotive properties of Miura-ori-type paper origami. The mechanics of a single paper crease is studied experimentally, and its non-elastic pro…
APPLIED COSMOGRAPHY: A Pedagogical Review
Yu. L. Bolotin, V. A. Cherkaskiy, O. Yu. Ivashtenko +2
Based on the cosmological principle only, the method of describing the evolution of the Universe, called cosmography, is in fact a kinematics of cosmological expansion. The effecti…
