If gravitational waves traveled through a medium filled with sticky dark matter, then the wave amplitude would be (weakly) damped. The analysis of this effect could shed new light on the nature of dark matter - argues Prof. Marek Biesiada (NCBJ) together with Chinese colleagues in a work published in the MNRAS Letters journal.

An international team of astrophysicists has discovered a giant black hole hidden among dust in a galaxy that already existed 1.4 billion years after the Big Bang. This is one of the first results of a project called Herschel Extragalactic Legacy Project (HELP). The lead co-author of the work is dr hab. Katarzyna Małek from the NCBJ Astrophysics Department.

The map published in the journal Astronomy & Astrophysics reveals more than 25,000 active supermassive black holes in distant galaxies. It is the result of a survey of the sky carried out over radio frequencies. Dr hab. Katarzyna Małek from the NCBJ Astrophysics Division participated in the preparation of the work.

Ph.D. Anna Durkalec from the NCBJ Astrophysics Division belongs to the group of 12 associate professors awarded in the Institute in 2020. Dr. Durkalec begins the description of her research by asking a few questions.

Heavily dust-obscured ultramassive star-forming galaxies in the early Universe contributed significantly to the cosmic star formation rate. But, how did such objects manage to build up their stellar masses at a relatively short time? Were they once starburst galaxies or were they gradually forming stars, exhausting their hydrogen reservoirs?

Three NCBJ scientists received NCN SONATA BIS grants, which will allow them to build or strengthen their own research groups at the Institute. The project entitled "DINGLE - Dust IN Galaxies: Looking through its Emission" was prepared by Dr. Ambra Nanni from the NCBJ Astrophysics Division. The author explains its assumptions:
