Searching for Jet Emission in LMXBs: A Polarimetric View
Galaxies, 2017 We present results taken from a study aiming at detecting the emission from relativistic particles jets in neutron star-low mass X-ray binaries using optical polarimetric observations.

Black hole accretion disc impacts [PDF]
, 2015 We present an analytic model for computing the luminosity and spectral evolution of flares caused by a supermassive black hole impacting the accretion disc of another supermassive black hole.

Hematopoietic (stem) cells—The elixir of life?
FEBS Letters, EarlyView.The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.

Is the disc thermal state controlling the Blandford & Znajek/Blandford & Payne jet dichotomy?
EPJ Web of Conferences, 2013 It is generally assumed that Blandford & Payne jets can carry a significant fraction of the accretion power released in the underlying disc. But this fraction actually strongly depends on the disc aspect ratio h/r, hence on the disc thermal properties ...

The Physical Relation between Disc and Coronal Emission in Quasars
Frontiers in Astronomy and Space Sciences, 2018 We propose a modified version of the observed non-linear relation between the X-ray (2 keV) and the ultraviolet (2,500 Å) emission in quasars (i.e., LX∝LUVγ) which involves the full width at half-maximum, FWHM, of the broad emission line, i.e., LX∝LUVγ ...

Accretion disc around black hole in Einstein-SU(N) non-linear sigma model
European Physical Journal C: Particles and Fields, 2023 The accretion of matter onto celestial bodies like black holes and neutron stars is a natural phenomenon that releases up to $$40\%$$ 40 % of the matter’s rest-mass energy, which is considered a source of radiation.

Observational Implications of OJ 287’s Predicted 2022 Disk Impact in the Black Hole Binary Model
Galaxies, 2023 We present a summary of the results of the OJ 287 observational campaign, which was carried out during the 2021/2022 observational season. This season is special in the binary model because the major axis of the precessing binary happens to lie almost ...

, 2017 We study the three-dimensional evolution of a viscous protoplanetary disc which accretes gas material from a second protoplanetary disc during a close encounter in an embedded star cluster.

Episodic accretion: the interplay of infall and disc instabilities [PDF]
, 2017 Using zoom-simulations carried out with the adaptive mesh-refinement code RAMSES with a dynamic range of up to $2^{27} \approx 1.34 \times 10^8$ we investigate the accretion profiles around six stars embedded in different environments inside a (40 pc)$^3$
