The galaxy, 3C 348, is a supergiant elliptical galaxy. [3][4] It is located inside a poor galaxy cluster with an X-ray luminosity of L bol = 4.8 × 10 37 W. [5] 3C 348 is classified as type E3 to E4 of the updated Hubble–de Vaucouleurs extended galaxy morphological classification scheme.

This Hubble Space Telescope composite of V and I filters shows the active galaxy 3C 348, also known as Hercules A. The Hubble data were taken in October of 2012.

2012年11月29日 · This VLA radio composite image shows the active galaxy 3C 348, also known as Hercules A. The VLA data, which record frequencies from 4-9 GHz, were taken in 2010-2011.

2012年11月29日 · But the innocuous-looking galaxy, also known as 3C 348, has long been known as the brightest radio-emitting object in the constellation Hercules. Emitting nearly a billion times more power in radio wavelengths than our Sun, the galaxy is one of the brightest extragalactic radio sources in the entire sky.

This VLA radio composite image shows the active galaxy 3C 348, also known as Hercules A. The VLA data, which record frequencies from 4-9 GHz, were taken in 2010-2011. The image was created from Hubble data from proposal 13065: S. Baum and C. O'Dea (Rochester Institute of Technology) and J. Stoke and F. Lo (Associated Universities, Inc.).

2002年5月1日 · Hercules A is one of a few powerful double-lobe radio sources that show unusual features, from a double optical core to a string of radio intensity rings in one of its two lobes.

2012年11月29日 · But the innocuous-looking galaxy, also known as 3C 348, has long been known as the brightest radio-emitting object in the constellation Hercules. Emitting nearly a billion times more power in radio wavelengths than our Sun, the galaxy is one of the brightest extragalactic radio sources in the entire sky.

1999年9月27日 · We investigate the X-ray properties of the powerful radio galaxy Hercules A (3C 348) using ROSAT HRI, PSPC and ASCA observations. The ASCA data are well fit by a thermal plasma model with a temperature of about 4.3 keV and abundances 0.4 solar. The HRI observation clearly reveals extended and elongated X-ray emission.

2012年11月29日 · This Hubble Space Telescope composite of V and I filters shows the active galaxy 3C 348, also known as Hercules A. The Hubble data were taken in October of 2012.

2025年3月7日 · In order to investigate the physical properties of these sources, the cloudy program was used to simulate the 3C 348 radio source outlook ionisation model, and it was found that its optical emission in the nuclear region is significantly lower than the theoretical prediction, which suggests the existence of an obscuration effect, which was ...
