ABSTRACT FRB 20220912A is a repeating Fast Radio Burst (FRB) that was discovered in Fall 2022 and remained highly active for several months. We report the detection of 35 FRBs from 541 h follow-up observations this source using recently refurbished Allen Telescope Array, covering 1344 MHz bandwidth primarily centred at 1572 MHz. All were detected lower half band with non-detections upper covered fluences 4–431 Jy-ms (median = 48.27 Jy-ms). find consistency previous repeater studies range...
Debris disks are dusty, optically thin structures around main sequence stars. HD 106906AB is a short-period stellar binary, host to wide separation planet, 106906b, and debris disk. Only few known systems include disk directly imaged 106906 the only one in which planet exterior The edge-on highly asymmetric scattered light. Here we resolve structure at resolution of 0.38" (39 au) with Atacama Large Millimeter/submillimeter Array (ALMA) wavelength 1.3 mm. We model both narrow broad ring...
Abstract RZ Piscium (RZ Psc) is well known in the variable star field because of its numerous irregular optical dips past 5 decades, but nature system heavily debated literature. We present multiyear infrared monitoring data from Spitzer and WISE to track activities inner debris production, revealing stochastic variability as short weekly timescales that consistent with destroying a 90 km sized asteroid every year. ALMA 1.3 mm combined spectral energy distribution modeling show disk compact...
