TL;DR: In this paper, the authors presented a study of galactic outflows driven by stellar feedback, where they extracted main-sequence disc galaxies with stellar mass 109 ≤ M⋆/M⊙ ≤ 5.7 × 1010 at redshift z = 0 from the highest resolution cosmological simulation of the Evolution and Assembly of GaLaxies and their Environments (EAGLE) set and compared to observations of disc galaxies obtained with the Sydney-AAO (Australian Astronomical Observatory) Multi-object Integral field spectrograph (SAMI).

TL;DR: In this article, the authors used the machine learning algorithm $XGBoost$ to estimate the ages of 250,000 stars taken from GALAH DR3 using only their overall metallicity and chemical abundances.

TL;DR: In this paper, the authors used the HERMES spectrograph at the Anglo Australian telescope to obtain spectra of 794 stars of the Orion complex to derive precise atmospheric parameters and chemical abundances of 25 elements for 15 stellar clusters.

TL;DR: In this paper, the authors used two-point auto-, cross-, and mark-correlation functions to investigate the extent to which small-scale clustering properties of star-forming galaxies can be used to gain physical insight into galaxy-galaxy interactions between galaxies of similar optical brightness and stellar mass.

TL;DR: In this article, the stellar and gas kinematics of the brightest group galaxies (BGGs) in dynamically relaxed and unrelaxed galaxy groups for a sample of 154 galaxies in the SAMI galaxy survey were studied.
