Titolo: | The study of extended emission in a radio galaxy detected in the LOFAR Two-Metre Sky Survey | Autori: | Thwala, S. A. Shafi, N. Colafrancesco, S. GOVONI, FEDERICA MURGIA, MATTEO |
Data pubblicazione: | 2019 | Rivista: | MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY | Numero: | 485 | Fascicolo: | 2 | Da pagina:: | 1938 | Abstract: | We performed a search for extended radio sources in the Low-Frequency Array Two-Meter Survey HETDEX Spring Field, and we were able to identify 11 low-brightness extended sources. In this paper we focus on the poorly studied radio galaxy PGC2285791, presenting a detailed analysis of its core, its two extended radio lobes, a spectral index map between 141 and 1400 MHz, and the multifrequency association with its IR and optical counterparts. Our results led to the identification of this source with a z = 0.14 extended radio galaxy exhibiting bubble-like radio lobe structures (∼6 arcmin in the S-N direction). | URI: | http://hdl.handle.net/20.500.12386/29931 | URL: | https://academic.oup.com/mnras/article/485/2/1938/5308838 | ISSN: | 0035-8711 | DOI: | 10.1093/mnras/stz347 | Bibcode ADS: | 2019MNRAS.485.1938T | Fulltext: | open |
