We explore three sets of cosmological hydrodynamical simulations, IllustrisTNG, EAGLE, and SIMBA, to investigate the physical processes impacting distribution baryons in around haloes across an unprecedented mass range $10^8<M_{\rm 200c}/{\rm M_{\odot}}<10^{15}$, from halo centre out scales as large $30\,R_{\rm 200c}$. demonstrate that baryonic feedback mechanisms significantly redistribute gas...

We perform a model-independent global fit to all $b \to s \ell \ell$ data in the light of recent measurements lepton flavour universality violating (LFUV) observables $R_{K_S^0}$ and $R_{K^{*+}}$ as well updated $B_s \phi \mu^+ \mu^-$ decay, by LHCb collaboration. obtain new physics (NP) solutions current anomalies data, assuming NP muon sector only. find that 1D scenarios $C_9^{\rm NP} <0 $ $C...

Tidal disruption events (TDEs) that occur in active galactic nuclei (AGN) with dusty tori are a special class of sources. TDEs can generate ultrafast and large opening-angle wind, which will almost inevitably collide the preexisting AGN few years later after TDE outburst. The wind-torus interactions drive two kinds shocks: bow shocks at windward side torus clouds, cloud inside clouds. In previo...

We present high resolution images of the Faraday Rotation Measure (RM) structure of the radio galaxy PKS1246-410 at the center of the Centaurus cluster. Comparison with Hα-line and soft X-ray emission reveals a correspondence between the line-emitting gas, the soft X-ray emitting gas, regions with an excess in the RM images, and signs of depolarization. Magnetic field strengths of 25 μG, organi...

A fundamental requirement for reionizing the Universe is that a sufficient fraction of ionizing photons emitted by galaxies successfully escapes into intergalactic medium. However, due to scarcity high-redshift observational data, sources driving reionization remain uncertain. In this work we calculate escape fractions ($f_{\rm esc}$) reionization-era from state-of-the-art THESAN simulations, w...
