- Deputy Director of SAI, Dr. Ol’ga Silchenko "The greatest works of women-astronomers in XIX-XX centuries" (40 min) I will made a brief review of the greatest works of professional astronomers which were women — the works that determined all the development of the astronomical picture of the world. Starting from the fundamental catalogues by Carolina Herschel, women-astronomers propagated the most laborious but also the most necessary astronomical surveys. Basic physical principles of the spectral classification of stars were founded by Antonia Maury and Annie J. Cannon, a key distance indicator — period-luminosity relation for Cepheids — was discovered by Henrietta S. Leavitt. The bold revelation of the dominant role of hydrogen in stars and in the Universe as a whole belongs to Cecilia Payne. The second half of the 20th century was strongly marked by the discovery of pulsars (neutron stars) by Jocelin Bell and by inventing evolutionary synthesis of integrated spectra of galaxies by Beatrice Tinsley. All these genius contributions into astronomy are first of all individual women achievements revealing mightiness of their intellect.
- Dr. Irina Voloshina "Women-astronomers of Sternberg Astronomical Institute" (15 min) Sternberg Astronomical Institute is a well-known astronomical institute not only in Moscow but in Russia and other countries. It is one of the departments of Lomonosov Moscow State University. 157 scientists from more than 20 laboratories and departments do their research in all fundamental fields of astronomy like stellar astrophysics, stellar astronomy, radioastronomy, galaxy and solar physics, lunar and planetary studies, relativistic astrophysics etc. 47 scientists are women, among them 33 are PhD and 7 are HDr. 41 girls-students study astronomy at the Faculty of Physics (from 112 students in total) and 6 PhD students. The Division of Astronomy includes 3 departments: 22 teachers, including 2 women. A few women-astronomers have been awarded for their achievements. A few minor planets are named in honor of our women-scientists.
- Dr. Anna Mel’nik "Different models of the Galactic spiral structure" (20 min) We consider models with regular two-armed spiral structure, models with multi-armed spiral pattern and models with elliptical outer rings forming near the Outer Lindblad resonance of the bar.
- Dr. Zhanna Rodionova "Women names on the maps of satellite and planets of Terrestian group" (20 min) The names of 24 famous women adopted by IAU for lunar craters are represented in the report. Women’s photoes and images of devoted them lunar crates are given also.
- Dr. Galina Lipunova "Logarithmic gravitational potential of the Schwarzschild Black Hole" (20 min) Approximate gravitational potentials are often used to describe analytically the motion of particles near black holes (BHs), as well as to study the structure of an accretion disk. Such "pseudo-Newtonian" potentials are used with the flat-metric equations. Here we consider the motion of a free particle near a non-rotating BH in the context of an exact "logarithmic" gravitational potential. We show how the logarithmic potential gives an exact solution for a mechanical problem and present the relativistic Bernoulli equation for the fluid in the Schwarzschild metric.
- Dr. Maria Pruzinskaya "Anomaly detection in the Open Supernova Catalog with machine learning techniques" (20 min) In the coming decade the large astronomical surveys will discover the millions of transients raising unprecedented data challenges in the process. Only the use of the machine learning algorithms can process such an amount of the data. Most of the discovered transients will belong to the known classes of astronomical objects. However, it is expected that some transients will be rare or completely new events of unknown physical nature. The task of finding them can be framed as an anomaly detection problem. We search for unusual light curves within the Open Supernova Catalog. Among the detected anomalies there are four superluminous supernovae, non-classical Type Ia SNe, two unusual Type II SNe, one active galactic nucleus SN2006kg, and one binary microlensing event Gaia16aye. We also find that 16 anomalies classified as supernovae in the literature can actually be stars or quasars. Our proposed pipeline represents an effective strategy to guarantee we shall not overlook exciting new science hidden in the data we fought so hard to acquire.
The winner is Dr. Zhanna Rodionova
