ALMA view of the 12C/13C isotopic ratio in starburst galaxies [PDF]

open access: yesAstronomy & Astrophysics, 2019
We derive molecular-gas-phase 12C/13C isotope ratios for the central few hundred parsecs of the three nearby starburst galaxies NGC 253, NGC 1068, and NGC 4945 making use of the λ ∼ 3 mm 12CN and 13CN N = 1–0 lines in the ALMA Band 3.

Evidence of AGN Activity in the Gamma-Ray Emission from Two Starburst Galaxies [PDF]

open access: yesAstrophysical Journal, 2019
Starburst galaxies are huge reservoirs of cosmic rays (CRs) and these CRs convert a significant fraction of their energy into gamma-rays by colliding with the interstellar medium (ISM).

The high energy X-ray probe: resolved X-ray populations in extragalactic environments

open access: yesFrontiers in Astronomy and Space Sciences, 2023
We construct simulated galaxy data sets based on the High Energy X-ray Probe (HEX-P) mission concept to demonstrate the significant advances in galaxy science that will be yielded by the HEX-P observatory.

Kinematics, Structure, and Mass Outflow Rates of Extreme Starburst Galactic Outflows

open access: yesThe Astrophysical Journal, 2023
We present results on the properties of extreme gas outflows in massive ( M _* ∼ 10 ^11 M _⊙ ), compact, starburst (star formation rate, SFR∼ 200 M _⊙ yr ^−1 ) galaxies at z = 0.4–0.7 with very high star formation surface densities (Σ _SFR ∼ 2000 M _⊙ yr

Clocking the Evolution of Post-starburst Galaxies: Methods and First Results [PDF]

open access: yesAstrophysical Journal, 2018
Detailed modeling of the recent star formation histories (SFHs) of post-starburst (or “E+A”) galaxies is impeded by the degeneracy between the time elapsed since the starburst ended (post-burst age), the fraction of stellar mass produced in the burst ...

РЕНТГЕНОВСКОЕ ИЗЛУЧЕНИЕ ГАЛАКТИК БЕЗ АКТИВНЫХ ЯДЕР

open access: yesOdessa Astronomical Publications, 2011
We perfirmed cross-correlation of SDSS galaxies and X-ray sources from 2XMMi catalogue. We selected galaxies with strong NII[6583] and OIII[5007] lines to divide them to starburst galaxies and AGNs.

Cosmic ray transport and radiative processes in nuclei of starburst galaxies [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2018
The high rate of star formation and supernova explosions of starburst galaxies make them interesting sources of high-energy radiation. Depending on the level of turbulence present in their interstellar medium, the bulk of cosmic rays produced inside ...

ALMA Millimeter/Submillimeter Sources among Spitzer SMUVS Galaxies at z > 2 in the COSMOS Field

open access: yesThe Astrophysical Journal, 2023
Submillimeter observations reveal the star formation activity obscured by dust in the young Universe. It still remains unclear how galaxies detected at submillimeter wavelengths are related to ultraviolet/optical-selected galaxies in terms of their ...

Large turbulent reservoirs of cold molecular gas around high-redshift starburst galaxies [PDF]

open access: yesNature, 2017
Starburst galaxies at the peak of cosmic star formation are among the most extreme star-forming engines in the Universe, producing stars over about 100 million years (ref. 2).
