Накратко на български

Далечни галактики и групи от тях, скрити зад облаци от прах, се търсят чрез инфрачервени и радиосигнали. Това помага да се разбере как са се формирали първите масивни структури във Вселената и колко звезди са се раждали в ранните ѝ етапи.

Far-Infrared to Radio Search for disTant Dust-obscUred galaxies and STructures

Massive dusty star-forming galaxies and galaxy protocluster contribute significantly to the cosmic star formation history in the early Universe and strongly ties to cosmology. These distant galaxies and structures trigger key questions that touch upon galaxy evolution and cosmology: How much star formation activities are obscured by dust in the early universe? How did galaxy clusters form and evolve before the cosmic noon? The FIRSTDUST project is dedicated to address these questions, aiming to 1) search for dusty star-forming galaxies out to z>6 and constrain cosmic star formation rate density; 2) discover distant galaxy groups and protoclusters at z>2 and investigate their properties to better understand their formation and evolution. To achieve these objectives, we need to produce a large galaxy catalog using deep astronomical images spanning from infrared to radio wavelengths, select distant dusty star-forming galaxies, and confirm their distant and dusty nature using spectroscopy. Meanwhile, we make use of infrared data from space telescopes and millimeter data from the advanced interferometry telescopes on the ground. This allows us to discover distant galaxy groups and protoclusters and study their star formation and interstellar mediums, shedding light on how massive galaxies and clusters form and evolve.

Цел на проекта

We are at a tipping point where unveiling the nature of distant dust-obscured galaxies and the formation of the first proto-clusters in our Universe is finally possible thanks to recent advances in multi-wavelength astronomy. Taking advantage of a unique ensemble of deep, large-area data sets from the far-infrared (FIR) to radio wavelengths in the COSMOS and H20 fields, I propose the project FIRSTDUST (Far-Infrared to Radio Search for disTant Dust-obscUred galaxies and STructures) that will provide: a complete characterization of the dust-obscured star-formation rate density (SFRD) at z = 2–6, and robust constraints on the contribution of previously undiscovered galaxy (proto)clusters to the SFRD. FIRSTDUST will also deliver the census of dusty star forming galaxies and proto-clusters, providing invaluable targets for the upcoming next-generation telescopes (e.g. JWST, E-ELT). I have unique expertise on producing multi-wavelength photometric catalogs by synthesizing data from IR and radio telescopes, and sophisticated data processing and measurement skills with (sub)mm interferometry (ALMA, NOEMA and ATCA). G. Magdis’ group at DTU Space has exclusive access to JWST MIRI GTO data and unique expertise to support the analysis with the FIR+(sub)mm data. The Cosmic Dawn Center (DAWN) has been constructing the largest, exclusive access data sets in the IR side and leading the 50 square degree DAWN survey, which is essential to this project. My dedicated work at DTU & DAWN is thus the best synergy to realize the proposed project.
