X3: A High-mass Young Stellar Object Close to the Supermassive Black Hole Sgr A*

چکیده

To date, the proposed observation of Young Stellar Objects (YSOs) in Galactic center (GC) still raises question where and how these objects could have formed due to violent vicinity Sgr~A*. Here, we report multi-wavelength detection a highly dynamic YSO close Sgr~A* that might be member IRS13 cluster. We observe beforehand known coreless bow-shock source X3 near- mid-infrared (NIR/MIR) with SINFONI (VLT), NACO ISAAC VISIR SHARP (NTT), NIRCAM2 (KECK). In radio domain, use CO continuum H30$\alpha$ ALMA observations identify system components at different temperatures locations concerning central stellar source. It is suggested radio/submm combination NIR Br$\gamma$ line can associated protoplanetary disk which consistent manifold reveal complex molecules elements such as PAH, SIV, NeII ArIII dense compact region. Based on photometric analysis, infer mass $15^{+10}_{-5} M_{\odot}$ for related age few $10^4$ yr. Due this estimate required relaxation time scales high-mass stars, finding an indication ongoing star formation inner parsec.

Collapse of a Rotating Supermassive Star to a Supermassive Black Hole: Analytic Determination of the Black Hole Mass and Spin

The collapse of a uniformaly rotating, supermassive star (SMS) to a supermassive black hole (SMBH) has been followed recently by means of hydrodynamic simulations in full general relativity. The initial SMS of arbitrary mass M in these simulations rotates uniformly at the mass–shedding limit and is marginally unstable to radial collapse. The final black hole mass and spin have been determined t...

A Relation between Supermassive Black Hole Mass and Quasar Metallicity?

We analyze spectra for a large sample of 578 Active Galactic Nuclei to examine the relationships between broad emission line properties and central supermassive black hole (SMBH) mass. We estimate SMBH masses by applying the virial theorem to the C IV λ1549 broad emission line. Although the FWHMs of C IV and Hβ appear nearly unrelated in individual objects, these FWHMs are well correlated when ...

The Low End of the Supermassive Black Hole Mass Function: Constraining the Mass of a Nuclear Black Hole in Ngc 205 via Stellar Kinematics

Hubble Space Telescope (HST) images and spectra of the nucleated dwarf elliptical galaxy NGC 205 are combined with 3-integral axisymmetric dynamical models to constrain the massMBH of a putative nuclear black hole. This is only the second attempt, after M33, to use resolved stellar kinematics to search for a nuclear black hole with mass below 10 solar masses. We are unable to identify a best-fi...

The radio spectrum of a quiescent stellar mass black hole

Observations of V404 Cyg performed with the Westerbork Synthesis Radio Telescope at four frequencies, over the interval 1.4−8.4 GHz, have provided us with the first broadband radio spectrum of a ‘quiescent’ stellar mass black hole. The measured mean flux density is of 0.35 mJy, with a spectral index α = +0.09±0.19 (such that Sν ∝ ν). Synchrotron emission from an inhomogeneous partially self-abs...

Properties of high-redshift quasars – I. Evolution of the supermassive black hole to halo mass ratio

In the local universe, the masses of Super-Massive Black-Holes (SMBH) appear to correlate with the physical properties of their hosts, including the mass of the dark-matter halos. At higher redshifts, we observe the growth of SMBHs indirectly through the identification of high redshift quasars. However information on their hosts is more difficult to obtain. In this paper we determine the masses...
