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

Post-starburst galaxies in SDSS-IV MaNGA [PDF]
Monthly notices of the Royal Astronomical Society, 2019 Post-starburst galaxies, identified by their unusually strong Balmer absorption lines and weaker than average emission lines, have traditionally been selected based on their central stellar populations. Here we identify 360 galaxies with post-starburst

Cosmic ray transport and radiative processes in nuclei of starburst galaxies [PDF]
Monthly 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 view of the 12C/13C isotopic ratio in starburst galaxies [PDF]
Astronomy & 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.

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

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

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

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

РЕНТГЕНОВСКОЕ ИЗЛУЧЕНИЕ ГАЛАКТИК БЕЗ АКТИВНЫХ ЯДЕР
Odessa 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.
