Published in 2020 at "Astronomy and Astrophysics"

DOI: 10.1051/0004-6361/202037814

Abstract: Context. The size and geometry of the broad-line region (BLR) in active galactic nuclei (AGNs) are among the main ingredients in determining the mass of the accreting black hole. Size and geometry can be constrained… read more here.

Published in 2020 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/staa2735

Abstract: Time lags due to X-ray reverberation have been detected in several Seyfert galaxies. The different traveltime between reflected and directly observed rays naturally causes this type of lag, which depends directly on the light-crossing time-scale… read more here.

Published in 2020 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/staa767

Abstract: New reverberation mapping (RM) measurements, combined with accurate luminosities and line ratios, provide strong constraints on the location of the line emitting gas in the broad line region (BLR) of active galactic nuclei (AGN). In… read more here.

Published in 2022 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stac2263

Abstract: Contemporary reverberation mapping campaigns are employing wide-area photometric data and high-multiplex spectroscopy to efficiently monitor hundreds of active galactic nuclei (AGN). However, the interaction of the window function(s) imposed by the observation cadence with the… read more here.

Published in 2023 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stad1136

Abstract: We compile optical and mid-infrared (MIR) light curves from the time-domain surveys (i.e., CRTS, PTF, ZTF and ASAS-SN) and WISE archive for a selected sample of active galactic nuclei (AGNs) with Hβ reverberation mapping (RM)… read more here.

Published in 2023 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stad1409

Abstract: We measure the black hole mass and investigate the accretion flow around the local (z = 0.0502) quasar PG 1119+120. Spectroscopic monitoring with Calar Alto provides Hβ lags and linewidths from which we estimate a black… read more here.

Published in 2024 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stae1063

Abstract: NGC 4395 is a dwarf Seyfert 1 galaxy with a possible intermediate-mass black hole of several $\rm {10^4}$ solar masses in its center. As a well-studied object, its broad line region size has been measured… read more here.

Published in 2017 at "Frontiers in Astronomy and Space Sciences"

DOI: 10.3389/fspas.2017.00031

Abstract: Over the past three decades reverberation mapping (RM) has been applied to about 100 AGNs. Their broad line region (BLR) sizes were measured and yielded mass estimates of the black holes in their center. However,… read more here.
