Distilling Graph Geometry: Knowledge Gap from GNNs to MLPs
Zhewei Chen, Hao Zhu, Jiaojiao Jiang +1
GNN-to-MLP distillation aims to retain the predictive accuracy of a message-passing teacher while deploying a graph-free MLP at inference. Existing methods mainly transfer node-wis…
HYPERION. The cold ISM of rapidly growing quasars: diverse gas reservoirs, dust enrichment, and feedback signatures
Claudia Maria Pierro, Roberta Tripodi, Laura Pentericci +11
Luminous QSOs at host some of the most rapidly assembled SMBHs in the early Universe. Characterizing their cold ISM is essential to determine their evolution. We investigate…
CIV wind properties of the SDSS-V X-ray selected quasars: strong optical-to-UV emission is key regardless of X-ray strength
Amy L. Rankine, David Homan, James Aird +25
We present an investigation of the rest-frame optical/UV and X-ray properties for a sample of 3027 X-ray selected quasars between detected in the deepest Spec…
A Cigale module tailored (not only) for Low-Luminosity AGN
I. E. López, G. Yang, G. Mountrichas +17
The spectral energy distribution (SED) of low-luminosity active galactic nuclei (LLAGN) presents challenges due to their faint emissions and the complexity of their accretion proce…
Accretion properties of X-ray AGN: Evidence for radiation-regulated obscuration with redshift-dependent host galaxy contribution
Brivael Laloux, Antonis Georgakakis, David M. Alexander +12
We adopt a Bayesian X-ray spectral approach to investigate the accretion properties of unobscured () and obscured ($22< \log(N_{\rm H}/{\rm cm}^…
Winds of change: the nuclear and galaxy-scale outflows and the X-ray variability of 2MASS 0918+2117
P. Baldini, G. Lanzuisi, M. Brusa +21
Powerful outflows from active galactic nuclei (AGN) can significantly impact the gas reservoirs of their host galaxies. However, it is still unclear how these outflows can propagat…
The SRG/eROSITA all-sky survey: Hard X-ray selected Active Galactic Nuclei
Sophia G. H. Waddell, J. Buchner, K. Nandra +12
The eROSITA instrument aboard the Spectrum Roentgen Gamma (SRG) satellite has performed its first all-sky survey between December 2019 and June 2020. This paper presents the result…
The eROSITA Final Equatorial Depth Survey (eFEDS): the hard X-ray selected sample
K. Nandra, S. G. H. Waddell, T. Liu +25
During its calibration and performance verification phase, the eROSITA instrument aboard the SRG satellite performed a uniform wide--area X-ray survey of approximately 140 deg$^{2}…
The SRG/eROSITA all-sky survey: First X-ray catalogues and data release of the western Galactic hemisphere
A. Merloni, G. Lamer, T. Liu +142
The eROSITA telescope array aboard the Spektrum Roentgen Gamma (SRG) satellite began surveying the sky in December 2019, with the aim of producing all-sky X-ray source lists and sk…
Ionised AGN outflows in the Goldfish galaxy -- The illuminating and interacting red quasar eFEDSJ091157.4+014327 at z 0.6
Blessing Musiimenta, Giovanna Speranza, Tanya Urrutia +12
Evolutionary models suggest that the initial growth phases of active galactic nuclei (AGN) are dust-enshrouded, and characterised by jet/wind outflows that should gradually clear t…
Multi-phase characterization of AGN winds in 5 local type-2 quasars
G. Speranza, C. Ramos Almeida, J. A. Acosta-Pulido +9
We present MEGARA (Multi-Espectrógrafo en GTC de Alta Resolución para Astronomía) Integral Field Unit (IFU) observations of 5 local type-2 quasars (QSO2s, z ) from the Qu…
A new discovery space opened by eROSITA: Ionised AGN outflows from X-ray selected samples
Blessing Musiimenta, Marcella Brusa, Teng Liu +21
In the context of an evolutionary model, the outflow phase of an Active Galactic Nuclei (AGN) occurs at the peak of its activity, once the central SMBH is massive enough to generat…
Warm molecular and ionized gas kinematics in the Type-2 quasar J0945+1737
G. Speranza, C. Ramos Almeida, J. A. Acosta-Pulido +11
We analyze Near-Infrared Integral Field Spectrograph (NIFS) observations of the type-2 quasar (QSO2) SDSS J094521.33+173753.2 to investigate its warm molecular and ionized gas kine…
The eROSITA Final Equatorial-Depth Survey (eFEDS): The first archetypal Quasar in the feedback phase discovered by eROSITA
M. Brusa, T. Urrutia, Y. Toba +18
Theoretical models of galaxy-AGN co-evolution ascribe an important role for the feedback process to a short, luminous, obscured, and dust-enshrouded phase during which the accretio…
The eROSITA Final Equatorial-Depth Survey (eFEDS): Identification and characterization of the counterparts to the point-like sources
M. Salvato, J. Wolf, T. Dwelly +41
In November 2019, eROSITA on board of SRG observatory started to map the entire sky in X-rays. After the 4-year survey program, it will reach flux limits about 25 times deeper than…
