Reduction of supernova light curves by vector Gaussian processes
Matwey V. Kornilov, T. A. Semenikhin, M. V. Pruzhinskaya
Bolometric light curves play an important role in understanding the underlying physics of various astrophysical phenomena, as they allow for a comprehensive modeling of the event a…
The SNAD Viewer: Everything You Want to Know about Your Favorite ZTF Object
Konstantin Malanchev, Matwey V. Kornilov, Maria V. Pruzhinskaya +9
We describe the SNAD Viewer, a web portal for astronomers which presents a centralized view of individual objects from the Zwicky Transient Facility's (ZTF) data releases, includin…
Supernova search with active learning in ZTF DR3
Maria V. Pruzhinskaya, Emille E. O. Ishida, Alexandra K. Novinskaya +9
We provide the first results from the complete SNAD adaptive learning pipeline in the context of a broad scope of data from large-scale astronomical surveys. The main goal of this…
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…
Useful relations for the analysis of stellar scintillation at the entrance pupil of a telescope
Victor Kornilov, Boris Safonov, Matwey Kornilov
The development of new techniques for characterizing atmospheric optical turbulence (OT) has become an active topic of research again in recent years. In order to facilitate these…
New SU UMa-type star ZTF18abdlzhd in the Zwicky Transient Facility data
Sergei V. Antipin, Alexandra M. Zubareva, Aleksandr A. Belinski +5
We carried out a search for unknown dwarf novae in a public data release of the Zwicky Transient Facility survey and suspected that the object ZTF18abdlzhd is a SU UMa-type star. P…
Anomaly detection in the Zwicky Transient Facility DR3
K. L. Malanchev, M. V. Pruzhinskaya, V. S. Korolev +11
We present results from applying the SNAD anomaly detection pipeline to the third public data release of the Zwicky Transient Facility (ZTF DR3). The pipeline is composed of 3 stag…
Active Anomaly Detection for time-domain discoveries
Emille E. O. Ishida, Matwey V. Kornilov, Konstantin L. Malanchev +7
We present the first evidence that adaptive learning techniques can boost the discovery of unusual objects within astronomical light curve data sets. Our method follows an active l…
Maximum likelihood estimation for disk image parameters
Matwey V. Kornilov
We present a novel technique for estimating disk parameters (the centre and the radius) from its 2D image. It is based on the maximal likelihood approach utilising both edge pixels…
Anomaly Detection in the Open Supernova Catalog
Maria V. Pruzhinskaya, Konstantin L. Malanchev, Matwey V. Kornilov +4
In the upcoming decade large astronomical surveys will discover millions of transients raising unprecedented data challenges in the process. Only the use of the machine learning al…
Fips: an OpenGL based FITS viewer
Matwey Kornilov, Konstantin Malanchev
FITS (Flexible Image Transport System) is a common format for astronomical data storage. It was first standardised in the early 1980s. Even though astronomical data is now processe…
Astronomical observation tasks short-term scheduling using PDDS algorithm
Matwey V. Kornilov
A concept of the ground-based optical astronomical observations efficiency is considered in this paper. We believe that a telescope efficiency can be increased by properly allocati…
Forecasting seeing and parameters of long-exposure images by means of ARIMA
Matwey V. Kornilov
Atmospheric turbulence is the one of the major limiting factors for ground-based astronomical observations. In this paper, the problem of short-term forecasting seeing is discussed…
Night-sky brightness and extinction at Mt. Shatdzhatmaz
V. Kornilov, M. Kornilov, O. Voziakova +6
The photometric sky quality of Mt. Shatdzhatmaz, the site of Sternberg Astronomical Institute Caucasian Observatory 2.5 m telescope, is characterized here by the statistics of the…
Resolved photometry of the binary components of RW Aur
S. Antipin, A. Belinski, A. Cherepashchuk +11
Resolved UBVRI photometry of RW Aur binary was performed on November 13/14, 2014 during the deep dimming of RW Aur with a newly installed 2.5 meter telescope of the Caucasus observ…
Prompt, early, and afterglow optical observations of five gamma-ray bursts (GRBs 100901A, 100902A, 100905A, 100906A, and 101020A)
E. S. Gorbovskoy, G. V. Lipunova, V. M. Lipunov +35
We present results of the prompt, early, and afterglow optical observations of five gamma-ray bursts, GRBs 100901A, 100902A, 100905A, 100906A, and 101020A, made with the Mobile Ast…
First results of site testing program at Mt. Shatdzhatmaz in 2007 - 2009
V. Kornilov, N. Shatsky, O. Voziakova +3
We present the first results of the site testing performed at Mt.~Shatdzhatmaz at Northern Caucasus, where the new Sternberg astronomical institute 2.5-m telescope will be installe…
