Hot, Photoionized X-ray Gas in Two Luminous Type 2 Quasars: Chandra-HST Evidence for a Wind-Driven Sequence
Anna Trindade Falcão, S. Kraemer, L. Feuillet +17
We present new Chandra/ACIS-S imaging spectroscopy of two luminous type 2 quasars, FIRST J120041.4+314745 (=0.116) and 2MASX J13003807+5454367 (=0.088), and compare their X-r…
High Resolution (<100pc) Ionization Structures in the ISM of AGN ESO~137-G34
D. Ł. Król, G. Fabbiano, M. Elvis +8
We present a detailed, spatially resolved { Veilleux \& Osterbrock (VO) diagram} analysis of ESO\,137-G034, a Compton-thick Active Galactic Nucleus (AGN), based on narrowband {\it…
The X-ray Emission of NGC 5005: An Unobscured Low-Luminosity AGN with a Weakly Accreting Broad-Line Region
Anna Trindade Falcão, R. Middei, G. Fabbiano +5
We present deep Chandra X-ray observations of NGC 5005, a LINER-dominated galaxy previously reported to host a broad H emission line. The diffuse soft X-ray emission (3 keV)…
HYPERION: broad-band X-ray-to-near-infrared emission of Quasars in the first billion years of the Universe
I. Saccheo, A. Bongiorno, E. Piconcelli +41
We aim at characterizing the X-ray-to-optical/near-infrared broad-band emission of luminous QSOs in the first Gyr of cosmic evolution to understand whether they exhibit differences…
Deep Chandra Observations of NGC 5728. III: Probing the High-Resolution X-ray Morphology and Multiphase ISM Interactions in the Circumnuclear Region
Anna Trindade Falcao, G. Fabbiano, M. Elvis +2
We present a detailed imaging analysis of 260 ks of sub-arcsecond resolution Chandra Advanced CCD Imaging Spectrometer (ACIS-S) observations of the nearby Seyfert 2 galaxy NGC 5728…
Hubble Space Telescope Observations of Nearby Type 1 Quasars. I. Characterisation of the Extended [O III] 5007Å Emission
Anna Trindade Falcão, S. B. Kraemer, T. C. Fischer +13
We use the Hubble Space Telescope to analyse the extended [O III] 5007A emission in seven bright radio-quiet type 1 quasars (QSO1s), focusing on the morphology and physical conditi…
HYPERION. Shedding light on the first luminous quasars: A correlation between UV disc winds and X-ray continuum
A. Tortosa, L. Zappacosta, E. Piconcelli +41
One of the main open questions in the field of luminous () quasars (QSOs) at is the rapid formation (Gyr) of their superm…
X-ray view of a massive node of the Cosmic Web at z~3 I. An exceptional overdensity of rapidly accreting SMBHs
A. Travascio, S. Cantalupo, P. Tozzi +16
Exploring SMBH population in protoclusters offers valuable insights into how environment affects SMBH growth. However, research on AGN within these areas is still limited by the sm…
Cosmic Himalayas: The Highest Quasar Density Peak Identified in a 10,000 deg Sky with Spatial Discrepancies between Galaxies, Quasars, and IGM HI
Yongming Liang, Masami Ouchi, Dongsheng Sun +27
We report the identification of a quasar overdensity in the BOSSJ0210 field, dubbed Cosmic Himalayas, consisting of 11 quasars at , the densest overdensity of quasars…
Quasars as standard candles III. Validation of a new sample for cosmological studies
E. Lusso, G. Risaliti, E. Nardini +15
We present a new catalogue of ~2,400 optically selected quasars with spectroscopic redshifts and X-ray observations from either Chandra or XMM-Newton. The sample can be used to inv…
X-ray Photons in the CO 2-1 'Lacuna' of NGC 2110
G. Fabbiano, A. Paggi, M. Elvis
A recent ALMA study of the Seyfert 2 Active Galactic Nucleus (AGN) NGC 2110 by Rosario et al. (2019) has reported a remarkable lack of CO 2-1 emission from the circumnuclear region…
