Astronomers Used a Fast Radio Burst to Probe the Structure of the Milky Way universetoday storybywill
, supported the theory that FRBs are likely caused by stellar remnants with extreme magnetic fields . However, the new DSA observations show that FRBs have diverse origins . The results also suggest that if FRBs are emitted by magnetars, they are likely formed through multiple unknown pathways. As Ravi said in a Caltech“We were puzzled at first about why we were discovering so many FRBs. But it comes down to careful engineering of the antennas and receivers, and the software pipelines.
The DSA will become even more powerful in the future as all 110 dishes come online . Caltech and its partners also plan to build an array of 2,000 radio dishes to create the DSA-2000, which will be the most powerful radio survey telescope ever built. The project would process data at a rate equivalent to roughly 20 percent of today’s global internet traffic . It will also detect an estimated one billion new radio sources, including 40,000 new FRBs .
Caltech professor Gregg Hallinan, the director of the Owens Valley Radio Observatory, will be the principal investigator of DSA-2000. “The DSA-2000 will build upon progress with the DSA and revolutionize radio astronomy,” he said.

Brightest Cluster Galaxy Formation in the z=4.3 Protocluster SPT2349-56: Discovery of a Radio-Loud AGNWe have observed the z=4.3 protocluster SPT2349-56 with ATCA with the aim of detecting radio-loud active galactic nuclei (AGN) amongst the ~30 submillimeter galaxies identified in the structure. We detect the central complex of SMGs at 2.2\,GHz with a luminosity of L_2.2=(4.42pm0.56)x10^{25} W/Hz. The ASKAP also detects the source at 888 MHz, constraining the radio spectral index to alpha=-1.6pm0.3, consistent with ATCA non-detections at 5.5 and 9GHz, and implying L_1.4(rest)=(2.4pm0.3)x10^{26}W/Hz. This radio luminosity is about 100 times higher than expected from star formation, assuming the usual FIR-radio correlation, which is a clear indication of an AGN driven by a forming brightest cluster galaxy (BCG). None of the SMGs in SPT2349-56 show signs of AGN in any other diagnostics available to us (notably 12CO out to J=16, OH163um, CII/IR, and optical spectra), highlighting the radio continuum as a powerful probe of obscured AGN in high-z protoclusters. No other significant radio detections are found amongst the cluster members, consistent with the FIR-radio correlation. We compare these results to field samples of radio sources and SMGs, along with the 22 SPT-SMG gravitational lenses also observed in the ATCA program, as well as powerful radio galaxies at high redshifts. Our results allow us to better understand the effects of this gas-rich, overdense environment on early supermassive black hole (SMBH) growth and cluster feedback. We estimate that (3.3pm0.7)x10^{38} W of power are injected into the growing ICM by the radio-loud AGN, whose energy over 100Myr is comparable to the binding energy of the gas mass of the central halo. The AGN power is also comparable to the instantaneous energy injection from supernova feedback from the 23 catalogued SMGs in the core region of 120kpc projected radius. The SPT2349-56 radio-loud AGN may be providing strong feedback on a nascent ICM.
