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.

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 ...

Janus kinase 2 inhibition by pacritinib as potential therapeutic target for liver fibrosis
Hepatology, EarlyView., 2022 Diagram of the activation of the profibrotic and procontractile Janus kinase 2 (JAK2)/Ras homolog family member A/Rho‐kinase pathway and the inhibition of phosphorylated JAK2 by pacritinib to inhibit hepatic stellate cell activity. Abstract Background and Aims Janus kinase 2 (JAK2) signaling is increased in human and experimental liver fibrosis with ...

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 ...

Gas Accretion Can Drive Turbulence in Galaxies
The Astrophysical Journal, 2023 The driving of turbulence in galaxies is deeply connected with the physics of feedback, star formation, outflows, accretion, and radial transport in disks.

Chemodynamic evidence of pristine gas accretion in the void galaxy VGS 12
Astronomy & AstrophysicsContext. Accretion of metal-poor gas is expected to be an important channel of gas replenishment in galaxy evolution studies. However, observational evidence of this process is still relatively scarce. Aims. The unusual polar disk galaxy VGS 12 was found
