Eso 422-g028: the Host Galaxy of a Grg
نویسنده
چکیده
Abstract. ESO422-G028 denotes the very center cD-galaxy of the giant radio source B0503-286 (Saripalli et al. 1986, Subrahmanya & Hunstead, 1986). The angular extent of the associated radio structure is about 42.4, which corresponds to a linear size of 1.89Mpc (with ΩM = 0.27, ΩΛ = 0.73, and H0 = 71 km s Mpc). Here we present new highfrequency total-power and polarization radio maps obtained with the Effelsberg 100-m dish. In addition, we correlate the radio data with optical and X-ray observations to investigate the physical conditions of both, the host galaxy and the extended structure.

Understanding the environment around the intermediate mass black hole candidate ESO 243-49 HLX-1
Aims. ESO 243-49 HLX-1, otherwise known as HLX-1, is an intermediate mass black hole (IMBH) candidate located 8 (3.7 Kpc) from the centre of the edge-on S0 galaxy ESO 243-49. How the black hole came to be associated with this galaxy, and the nature of the environment in which it resides, are still unclear. Using multi-wavelength observations we investigate the nature of the medium surrounding H...
متن کاملThe galaxies in the field of the nearby GRB 980425 / SN 1998 bw
We present spectroscopic observations of ESO 184−G82, the host galaxy of GRB 980425/SN 1998bw, and six galaxies in its field. A host redshift of z = 0.0087± 0.0006 is derived, consistent with that measured by Tinney et al. (1998). Redshifts are obtained for the six surrounding galaxies observed. Three of these galaxies lie within 11 Mpc of each other, confirming the suggestion that some of thes...

The aim of the present work is detection of galaxy clusters based on weak gravitational lensing method. We apply mass aperture statistics method to 0.32 square degrees data obtained with the WFI@MPG/ESO 2.2 m telescope and detect mass peaks based on their mass not the luminosity. So by the application of proper filter function, shear profile and mass map are produced. Finally mass peaks with hi...
متن کاملTOPOLOGY OPTIMIZATION OF DOUBLE LAYER GRIDS FOR EARTHQUAKE LOADS USING A TWO-STAGE ESO-ACO METHOD
A two-stage optimization method is presented by employing the evolutionary structural optimization (ESO) and ant colony optimization (ACO), which is called ESO-ACO method. To implement ESO-ACO, size optimization is performed using ESO, first. Then, the outcomes of ESO are employed to enhance ACO. In optimization process, the weight of double layer grid is minimized under various constraints whi...
متن کاملSpatial decomposition of on-nucleus spectra of quasar host galaxies
In order to study the host galaxies of type 1 (broad-line) quasars, we present a semi-analytic modelling method to decompose the on-nucleus spectra of quasars into nuclear and host galaxy channels. The method uses the spatial information contained in long-slit or slitlet spectra. A routine determines the best fitting combination of the spatial distribution of the point like nucleus and extended...
