Gone with the wind? Potential gas inflow in the broad-line region of a QSO at traced by time-varying Balmer absorption
Xihan Ji, Dominic J. Walton, Francesco D'Eugenio +6
We report spectroscopic observations of a remarkable QSO, J115724.80-000455.56 at from the Dark Energy Spectroscopic Instrument (DESI) survey. This QSO exhibits variabili…
Reigniting the FUSE II: O VI Emission in Massive Elliptical Galaxies
Michael Reefe, Michael McDonald, Greg L. Bryan +6
This is the second paper in a series where we examine archival far-ultraviolet spectroscopy of 29 massive elliptical galaxies from the Far Ultraviolet Spectroscopic Explorer (FUSE)…
Mapping Gas Accretion and Stellar Kinematics to Sub-kiloparsec Scales in NGC 4696 with JWST/NIRSpec
Mathieu Marquis, Julie Hlavacek-Larrondo, Olivia Pereira +35
We present JWST/NIRSpec IFU spectroscopy of the central pc () of NGC 4696, the BCG in the Centaurus cluster. Leveraging the (…
JWST reveals how black holes are fed: kiloparsec-scale multiphase filaments feed sub-kiloparsec circumnuclear disks
Julie Hlavacek-Larrondo, Hyunseop Choi, Minghao Guo +35
The Centaurus cluster is one of the most important archetypes of radio-mode AGN feedback, with its central galaxy, NGC 4696, launching powerful jets that inflate X-ray cavities and…
Blueshifted lines from the inner accretion disc's rotation can explain quasar absorption "forests''
Amelia M. Hankla, Fergus J. E. Baker, Daniel R. Wilkins +1
Recent XRISM observations of active galactic nuclei such as PDS 456 have revealed ``forests'' of absorption lines best modeled by five distinct absorption zones with varying large…
The Cliff: A Metal-Poor Little Red Dot Hosting an Overmassive Black Hole at
Lucy R. Ivey, Francesco D'Eugenio, Roberto Maiolino +18
JWST has revealed a large population of massive black holes (BHs) in the early Universe with unusual properties which mark them as distinct from low-redshift active galactic nuclei…
Signatures of star formation inside galactic outflows
Dily Duan Yi Ong, Francesco D'Eugenio, Roberto Maiolino +13
Observations have suggested that galactic outflows contain substantial amounts of dense and clumpy molecular gas, creating favourable conditions for igniting star formation. Indeed…
BlackTHUNDER: Evidence of three massive black holes in a z~5 galaxy
Hannah Übler, Giovanni Mazzolari, Roberto Maiolino +41
We present observational evidence of three massive, accreting black holes (BHs) in the z=5.0167 galaxy J0148-4214 from JWST/NIRSpec-IFU spectroscopy. The BHs are revealed through b…
A black hole in a near-pristine galaxy 700 million years after the Big Bang
Roberto Maiolino, Hannah Uebler, Francesco D'Eugenio +36
The recent discovery of a large number of massive black holes within the first two billion years after the Big Bang, as well as their peculiar properties, have been largely unexpec…
estimating the spin of MAXI J1348--630 from intermediate and soft states using \textit{Insight}-HXMT data
J. Guan, R. C. Ma, L. Tao +6
We present a broadband spectral analysis of the soft-intermediate and soft states using \textit{Insight}-HXMT observations of the black hole binary MAXI J1348--630 during its outbu…
Can AGN feedback-driven star formation explain the size evolution of massive galaxies?
W. Ishibashi, A. C. Fabian, R. E. A. Canning
Observations indicate that massive galaxies at z~2 are more compact than galaxies of comparable mass at z~0, with effective radii evolving by a factor of ~3-5. This implies that ga…
Warm absorbers in active galactic nuclei
C. S. Reynolds, A. C. Fabian
Recent {\it ASCA} observations confirm the presence of X-ray absorption due to partially ionized gas in many Seyfert 1 galaxies; the so-called warm absorber. Constraints on the loc…
