EPJ Web of Conferences, 2012 Cosmology requires at least half of the baryons in the Universe to be in the intergalactic medium, much of which is believed to form hot coronae around galaxies. Star-forming galaxies must be accreting from their coronae.

Black holes regulate cool gas accretion in massive galaxies. [PDF]
Nature, 2023 Abstract The nucleus of almost all massive galaxies contains a supermassive black hole (BH) 1 . The feedback from the accretion of these BHs is often considered to have crucial roles in establishing the quiescence of massive galaxies 2–14

JWST interferometric imaging reveals the dusty torus obscuring the supermassive black hole of Circinus galaxy [PDF]
Nature CommunicationsThe dusty and molecular torus is an elusive structure surrounding supermassive black holes, yet its importance is unequivocal for understanding feedback and accretion mechanisms.

Potential impact of the Sagittarius dwarf galaxy on the formation of young O-rich stars [PDF]
Nature CommunicationsThe Milky Way underwent significant transformations in its early history, characterised by violent mergers and satellite galaxy accretion. However, recent observations reveal notable star formation events over the past 4 Gyr, likely triggered by ...

Accretion of galaxy groups into galaxy clusters [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT We study the role of group infall in the assembly and dynamics of galaxy clusters in ΛCDM. We select 10 clusters with virial mass M200 ∼ 1014 $\rm M_\odot$ from the cosmological hydrodynamical simulation Illustris and follow their galaxies with stellar mass M⋆ ≥ 1.5 × 108 $\rm M_\odot$.

Cold gas accretion in galaxies [PDF]
The Astronomy and Astrophysics Review, 2008 Evidence for the accretion of cold gas in galaxies has been rapidly accumulating in the past years. HI observations of galaxies and their environment have brought to light new facts and phenomena which are evidence of ongoing or recent accretion: 1) A large number of galaxies are accompanied by gas-rich dwarfs or are surrounded by HI cloud complexes ...

The Astrophysical Journal Supplement Series, 2023 The effects of metallicity on the evolution of protoplanetary disks may be studied in the outer Galaxy where the metallicity is lower than in the solar neighborhood.

SDSS-IV MaNGA: How Galaxy Interactions Influence Active Galactic Nuclei
The Astrophysical Journal, 2023 We present a comparative study of active galactic nuclei (AGN) between galaxy pairs and isolated galaxies with the final data release of the MaNGA integral field spectroscopic survey.

How Ram Pressure Drives Radial Gas Motions in the Surviving Disk
The Astrophysical Journal, 2023 Galaxy evolution can be dramatically affected by the environment, especially by the dense environment of a galaxy cluster. Recent observational studies show that massive galaxies undergoing strong ram-pressure stripping (RPS) have an enhanced frequency ...

Angular Momentum Accretion onto Disc Galaxies [PDF]
Proceedings of the International Astronomical Union, 2018 AbstractThroughout the Hubble time, gas makes its way from the intergalactic medium into galaxies fuelling their star formation and promoting their growth. One of the key properties of the accreting gas is its angular momentum, which has profound implications for the evolution of, in particular, disc galaxies.
