On measuring the Hubble constant with X-ray reverberation mapping of active galactic nuclei

Adam Ingram, Guglielmo Mastroserio, Michiel van der Klis +8

We show that X-ray reverberation mapping can be used to measure the distance to type 1 active galactic nuclei (AGNs). This is because X-ray photons originally emitted from the `cor…

Second Timescale Photometry of the Very Fast Nova V1674 Her with Palomar Gattini-IR

Kylie Y. Hansen, Kishalay De, Michael C. B. Ashley +15

We report second-timescale infrared photometry of the nova V1674 Her using Palomar Gattini-IR. These observations constitute the first infrared and highest temporal resolution data…

Evidence for an expanding corona based on spectral-timing modelling of multiple black hole X-ray binaries

Zheng Cao, Matteo Lucchini, Sera Markoff +2

Galactic black hole X-ray binaries (BHXBs) provide excellent laboratories to study accretion, as their relatively quick evolution allows us to monitor large changes in the in-flowi…

Modelling correlated variability in accreting black holes: the effect of high density and variable ionisation on reverberation lags

Guglielmo Mastroserio, Adam Ingram, Jingyi Wang +9

We present a new release of the RELTRANS model to fit the complex cross-spectrum of accreting black holes as a function of energy. The model accounts for continuum lags and reverbe…

A systematic study of photoionized emission and warm absorption signatures of the NLS1 Mrk 335

H. Liu, M. L. Parker, J. Jiang +4

We present an analysis of all the archival high resolution spectra of the Narrow-line Seyfert 1 galaxy Mrk~335 obtained with Reflection Grating Spectrometer (RGS) on board \textit{…

NICER uncovers the transient nature of the type-B quasi-periodic oscillation in the black hole candidate MAXI J1348-630

L. Zhang, D. Altamirano, P. Uttley +13

We present a systematic spectral-timing analysis of a fast appearance/disappearance of a type-B quasi-periodic oscillation (QPO), observed in four NICER observations of MAXI J1348-…
