The Discovery of Sgr A ∗
نویسنده
چکیده
The galactic center compact radio source Sgr A was discovered on 13 and 15 February 1974 by Bruce Balick and Robert L. Brown using the Green Bank 35 km radio link interferometer (Balick & Brown 1974). We discuss other observations of this source in the years 1965-1985. Early VLBI observations are described. The name Sgr A was first used by Robert L. Brown (1982) and has become the accepted name for the compact source at the center of the Milky Way.

Discovery of a New Soft Gamma Repeater , Sgr 1627 – 41
We report the discovery of a new soft gamma repeater (SGR), SGR 1627–41, and present BATSE observations of the burst emission and BeppoSAX NFI observations of the probable persistent Xray counterpart to this SGR. All but one burst spectrum are well fit by an optically thin thermal bremsstrahlung (OTTB) model with kT values between 25 and 35 keV. The spectrum of the X-ray counterpart, SAX J1635....

We report the results of X–ray (2–10 keV) observations of the giant molecular clouds Sgr B, Sgr C and Sgr D in the Galactic Center region, together with the discovery of the point-like source SAX J1748.2–2808. The data have been obtained with the MECS instrument on the BeppoSAX satellite. The core of Sgr B2 has an X–ray luminosity of ∼6×10 erg s and its spectrum is characterized by a strong Fe ...
متن کاملINTEGRAL discovery of persistent hard X - ray emission from the Soft Gamma Ray Repeater SGR 1806 – 20 ⋆
We report the discovery of persistent hard X-ray emission extending up to 150 keV from the soft gamma-ray repeater SGR 1806–20 using data obtained with the INTEGRAL satellite in 2003-2004. Previous observations of hard X-rays from objects of this class were limited to short duration bursts and rare transient episodes of strongly enhanced luminosity (“flares”). The emission observed with the IBI...
متن کاملHigh frequency oscillations during magnetar flares
The recent discovery of high frequency oscillations during giant flares from the Soft Gamma Repeaters SGR 1806-20 and SGR 1900+14 may be the first direct detection of vibrations in a neutron star crust. If this interpretation is correct it offers a novel means of testing the neutron star equation of state, crustal breaking strain, and magnetic field configuration. We review the observational da...

We report the discovery of complex high frequency variability during the August 27, 1998 giant flare from SGR 1900+14 using the Rossi X-ray Timing Explorer (RXTE). We detect an ≈ 84 Hz oscillation (QPO) during a 1 s interval beginning approximately 1 min after the initial hard spike. The modulation amplitude is energy dependent, reaching a maximum of 26% (rms) for photons above 30 keV, and is n...
