The Compton-thick AGN Population and the Distribution of Low-mass AGN in our Cosmic Backyard
A. Annuar, D. M. Alexander, P. Gandhi +21
We present a census of the Compton-thick (CT) active galactic nucleus (AGN) population and the column density () distribution of AGN in our cosmic backyard using a mid-…
Uncovering the geometry of the hot X-ray corona in the Seyfert galaxy NGC4151 with IXPE
V. E. Gianolli, D. E. Kim, S. Bianchi +106
We present an X-ray spectro-polarimetric analysis of the bright Seyfert galaxy NGC4151. The source has been observed with the Imaging X-ray Polarimetry Explorer (IXPE) for 700 ks,…
Revealing the relation between black-hole growth and host-galaxy compactness among star-forming galaxies
Q. Ni, W. N. Brandt, G. Yang +8
Recent studies show that a universal relation between black-hole (BH) growth and stellar mass () or star formation rate (SFR) is an oversimplification of BH-galaxy co-e…
Does black-hole growth depend fundamentally on host-galaxy compactness?
Q. Ni, G. Yang, W. N. Brandt +5
Possible connections between central black-hole (BH) growth and host-galaxy compactness have been found observationally, which may provide insight into BH-galaxy coevolution: compa…
Does black-hole growth depend on the cosmic environment?
Guang Yang, W. N. Brandt, B. Darvish +5
It is well known that environment affects galaxy evolution, which is broadly related to supermassive black hole (SMBH) growth. We investigate whether SMBH evolution also depends on…
The XMM-SERVS survey: new XMM-Newton point-source catalog for the XMM-LSS field
C. -T. J. Chen, W. N. Brandt, B. Luo +28
We present an X-ray point-source catalog from the XMM-Large Scale Structure survey region (XMM-LSS), one of the XMM-Spitzer Extragalactic Representative Volume Survey (XMM-SERVS) f…
Heavy X-ray obscuration in the most-luminous galaxies discovered by WISE
F. Vito, W. N. Brandt, D. Stern +11
Hot Dust-Obscured Galaxies (Hot DOGs) are hyperluminous () infrared galaxies with extremely high (up to hundreds of K) dust tempe…
Linking black-hole growth with host galaxies: The accretion-stellar mass relation and its cosmic evolution
G. Yang, W. N. Brandt, F. Vito +9
Previous studies suggest that the growth of supermassive black holes (SMBHs) may be fundamentally related to host-galaxy stellar mass (). To investigate this SMBH growth-$…
Hard X-ray selected AGNs in low-mass galaxies from the NuSTAR serendipitous survey
C. -T. J. Chen, W. N. Brandt, A. E. Reines +14
We present a sample of 10 low-mass active galactic nuclei (AGNs) selected from the 40-month NuSTAR serendipitous survey. The sample is selected to have robust NuSTAR detections at…
Reverberation Mapping of the Seyfert 1 Galaxy NGC 7469
B. M. Peterson, C. J. Grier, Keith Horne +43
A large reverberation mapping study of the Seyfert 1 galaxy NGC 7469 has yielded emission-line lags for Hbeta 4861 and He II 4686 and a central black hole mass measurement of about…
