DOI: 10.1038/s41550-019-0765-4
Abstract: The central nuclei of galaxies, where supermassive black holes (SMBHs) are thought to reside, can experience phases of activity when they become active galactic nuclei (AGNs). An AGN can eject winds and jets and produce… read more here.

DOI: 10.1093/mnras/stae1617
Abstract: Powerful supermassive black hole (SMBH) winds in the form of ultra-fast outflows (UFOs) are detected in the X-ray spectra of several active galactic nuclei (AGN) seemingly independently of their radio classification between radio quiet (RQ)… read more here.

DOI: 10.1093/mnras/stae1861
Abstract: Measuring the environments of massive galaxies at high redshift is crucial to understanding galaxy evolution and the conditions that gave rise to the distribution of matter we see in the Universe today. While high-z radio… read more here.

DOI: 10.1093/mnras/staf1946
Abstract: We searched the Hubble Space Telescope Cosmic Origins Spectrograph archive for ultraviolet spectra of 428 AGN to identify intrinsic N v absorption systems. We filtered out Type 2 AGN, blazars, and spectra that do not cover… read more here.

DOI: 10.1093/mnras/sty1802
Abstract: A small subset of optically selected radio-quiet quasars showing weak or no emission lines may turn out to be the elusive radio-quiet BL Lac objects, or simply be radio-quiet QSOs with a still-forming/shielded broad line… read more here.

DOI: 10.1093/mnras/stz3384
Abstract: The main objective of this work is to establish and interpret the dominant spectral components and their differences in radio-loud (RL) and radio-quiet (RQ) AGN with very massive black holes, and accreting at moderate rates.… read more here.

DOI: 10.1093/mnras/stz595
Abstract: A strong effort has been devoted to understand the physical origin of radio emission from low-luminosity AGN (LLAGN), but a comprehensive picture is still missing. We used high-resolution ($\le$1 arcsec), multi-frequency (1.5, 5.5, 9 and… read more here.

DOI: 10.1093/mnrasl/slad051
Abstract: Measuring the proper motion of the emission component in radio-quiet quasars (RQQs) could help to distinguish between the origins of the radio emission and to understand whether the jet production mechanism is the same in… read more here.

DOI: 10.3389/fspas.2024.1530392
Abstract: Active galactic nuclei (AGN) are powerful sources of panchromatic radiation. All AGN emit in X-rays, contributing around 5%–10% of the AGN bolometric luminosity. The X-ray emitting region, popularly known as the corona, is geometrically and… read more here.
