VizieR Online Data Catalog: ACS J1149.5+2223 LOFAR and VLA images (Bruno+, 2021)

We analysed archival Chandra X-ray data (first presented by Ogrean et al., 2016ApJ...819..113O) of MACS J1149, observed in VFAINT mode with ACIS-I.

We retrieved archival GMRT data (first presented by Bonafede et al., 2012MNRAS.426...40B) in the 305-340 MHz band, for a total bandwidth of 32MHz, split into 256 channels.

Observations of the LOFAR Two-meter Sky Survey (LoTSS; Shimwell et al. 2017, Cat. J/A+A/598/A104, 2019, Cat. J/A+A/622/A1 ) are particularly suitable for the detection of extended and low brightness diuse emission with steep spectrum, such as radio halos and radio relics.

MACS J1149 was observed with the JVLA at 1-2GHz (L-band) in B, C, and D configurations, for 5.5, 2.5, and 1.5 hours onsource time, respectively with 3C286 as flux density calibrator and J1150+2417 as phase calibrator.

The name of each radio map reports the instrument, the frequency, and the resolution. The name of the X-ray map reports the instrument and the band.
