Taming the derivative: diagnostics of the continuum and H emission in a prototypical Population B active galaxy
Swayamtrupta Panda, Edi Bon, Paola Marziani +1
We report preliminary results on the analysis of the continuum and H light curves of the type-1 active galactic nucleus (AGN) NGC 5548. We notice a clear signature of shallowing…
All-sky search for gravitational wave emission from scalar boson clouds around spinning black holes in LIGO O3 data
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1669
This paper describes the first all-sky search for long-duration, quasi-monochromatic gravitational-wave signals emitted by ultralight scalar boson clouds around spinning black hole…
Search for continuous gravitational waves from 20 accreting millisecond X-ray pulsars in O3 LIGO data
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1634
Results are presented of searches for continuous gravitational waves from 20 accreting millisecond X-ray pulsars with accurately measured spin frequencies and orbital parameters, u…
Multi-wavelength study of Mrk 421 during a TeV flare
A. Gokus, A. Kreikenbohm, K. Leiter +31
The blazar Mrk 421 shows frequent, short flares in the TeV energy regime. Due to the fast nature of such episodes, we often fail to obtain sufficient simultaneous information about…
Large optical modulations during 2018 outburst of MAXI J1820+070 reveal evolution of warped accretion disc through X-ray state change
Jessymol K. Thomas, Philip A. Charles, David A. H. Buckley +5
The black-hole X-ray transient MAXI J1820+07 (=ASSASN-18ey) discovered in March 2018 was one of the optically brightest ever seen, which has resulted in very detailed optical outbu…
Investigation of the correlation patterns and the Compton dominance variability of Mrk 421 in 2017
MAGIC Collaboration, V. A. Acciari, S. Ansoldi +284
We present a detailed characterisation and theoretical interpretation of the broadband emission of the paradigmatic TeV blazar Mrk 421, with special focus on the multi-band flux co…
