Mariusz Gromadzki

(Astronomical Observatory, University of Warsaw)

Mariusz was born and grew up in Łomża. He received his master's degree in astronomy from the Nicolaus Copernicus University in Toruń based on the work dedicated to study fast variability of symbiotic stars. He was continuing symbiotic stars research during PhD study at Nicolaus Astronomical Center in Warsaw but explored variability timescales increased from minutes and hours to years, decades and even centuries. After graduation, he shortly worked at the Space Research Centre in Warsaw and then move to Chile. During almost five years at Universidad de Valparaíso, he joined the VVV survey science team, his tasks were related to  searching high proper motion low mass stars and brown dwarfs towards extremely crowded Milky Way fields. He also followed up candidates for the coolest and the oldest brown dwarfs in the Galaxy using near-IR facilities installed on the largest telescopes in the Earth. 
Currently he is working at the Astronomical Observatory of University of Warsaw. His main scientific interests are connected with spectroscopic studies of various types of astrophysical transients, including supernovae, optical counterpart of gravitational wave source, tidal disruption events and other super massive black hole related transients. He is a member of the OGLE team, ePESSTO+ and ENGRAVE collaborations. He is probably the most active polish user of the South African Large Telescope thanks to participation
in  the large program entitled "Observing the Transient Universe".

Krzysztof Hełminiak

(Nicolaus Copernicus Astronomical Center, Toruń)

Krzysztof was born in Barlinek. He obtained his master's degree in astronomy from the Nicolaus Copernicus University in Toruń based on the work on astrometry of visual binaries with adaptive optics. In 2006 he started PhD studies at the NCAC Toruń, working on low-mass stars in binaries, under the supervision of Prof. Maciej Konacki. He obtained his PhD in October 2010, and immediately started his post-doc position at the Pontificia Universidad Catolica in Santiago, Chile. He extended his work on eclipsing binaries to other types of stars, and established the Comprehensive Research with Echelles on the Most interesting Eclipsing binaries (CREME) project, aimed at looking for and characterizing rare, unusual, and otherwise valuable stellar pairs. This work has been continued during his second post-doctoral term, at the Subaru Telescope in Hawaii. In 2016 Krzysztof came back to where he started - Toruń - to continue his work at the NCAC branch.

He is broadly interested in eclipsing binaries, their observations and modelling, as well as looking for planets around them. During his time in Chile and Hawaii, Krzysztof was also working in several large international collaborations, like the Vista Variables in Via Lactea (VVV), Strategic Exploration of Exoplanets and Disks with Subaru (SEEDS) or the Hyper-Supreme Cam (HSC) consortium, as well as helped in several other projects (e.g. HAT-South, Kepler). He is also involved in the Solaris project, namely in the search for circumbinary bodies with eclipse timing variations. He continues his work on precise characterization of eclipsing binaries, focusing on the satellite-borne observations with TESS and (future) PLATO missions. He is also one of the most active Polish astronomers in terms of proposals submitted to ESO.

His favorite aspect of the astronomer's job are the travels. Apart from Chile and Hawaii, his work duties (observations, conferences, scientific collaborations) took him for example to Australia, Argentina, South Africa, Brazil, or Japan.

Maciej Bilicki

(Center for Theoretical Physics of the Polish Academy of Sciences, Poland)

Maciej was born and grew up in Łódź (Lodz) right in the middle of Poland. Since childhood he was interested in astronomy and mathematics, and after finishing high school he decided to study mathematics with computer science at the University of Łódź. However, before (successfully) completing his MSc program there, he knew that he'd prefer to be an astronomer and not a mathematician or a computer scientist. He therefore took up yet another 5 years of MSc studies, this time in astronomy at the Nicolaus Copernicus University in Toruń (of which 1 year spent at the Warsaw University within the MOST program). Following successful summer internships at NCAC Warsaw under Prof. Michał Chodorowski's guidance, Maciej first wrote his MSc thesis in theoretical cosmology (2007) and then took up PhD studies at Bartycka 18 under Prof. Chodorowski's supervision. Maciej's PhD thesis defended in 2012 dealt with "Motion of the Local Group as a cosmological probe".
Over 2012-15 Maciej was a SARChI postdoctoral fellow at the Astronomy Department of the University of Cape Town in South Africa, working on observational cosmology and galaxy catalogs. Over that period he gained particular interest in applications of modern computer techniques, such as machine learning, to astronomy, and he's been working on these ever since. In 2015 Maciej moved to the Leiden Observatory in the Netherlands, staying there until early 2019 as a senior postdoctoral researcher, and extending his interests to other aspects of cosmology, including gravitational lensing. During that time he also kept his links with Poland and in particular over 2017-18 was a part-time assistant professor at the Astrophysics Division of the National Center for Nuclear Research in Warsaw.
In 2019 Maciej joined the Center for Theoretical Physics PAS in Warsaw, first as an assistant professor, and since 2021 as an associate professor. He is co-leading the Computational Cosmology Group there and continues working on observational cosmology, wide-angle galaxy catalogs and applications of computer science techniques to extragalactic astrophysics. He's an active member of several photometric and spectroscopic galaxy surveys, spanning from the optical to the radio domain.

He develops BEANS software, which he uses on a daily basis to analyze hundreds of terabytes of MOCCA data.
