Short answer: No and yes. Do ASKAP and/or ALMA have "fast dump" interferometric modes? Or do they have at least some way to extract dispersion of transient events at the millisecond level? ASKAP has FREDDA which searches in total-intensity filterbanks (aka dynamic spectra) and triggers the voltages for imaging or localizing the FRB. general ...

The progenitors of FRBs have been tied to soft gamma-ray repeaters (SGRs), and are likely young magnetars displaying irregular atmospheric and magnetic activity. The earliest connection between the two - as far as I know - was made by Lyutikov (2002), who compared the outbursts to solar flares (the magnetar bursts are sometimes referred to as "giant pulses"),...

The publication describing the original detection of the first known FRB (Lorimer, D. R., Bailes, M., McLaughlin, M. A., Narkevic, D. J. & Crawford, F.: A Bright Millisecond Radio Burst of Extragalactic Origin. arXiv:0709.4301) has a plot of the measurement that makes the effects of dispersion on this particular FRB nicely visible. Take a look at Fig. 2 ...

You'd be right to be a little suspicious if CHIME had just detected two events. Fortunately, that's not typically the detection criterion for a repeating FRB. In the case you're talking about, FRB 180814.J0422+73 (Amiri et al. 2019 for the CHIME/FRB Collaboration), six bursts were detected from one particular region, with only 18 total bursts detected in ...

Answer posted under the wire during closure. Others may be able to write an additional and/or different answer as soon as two more reopen votes are cast. Would it have been possible to send a radio signal towards ʻOumuamua? Yes. It is certainly true that at any time, a large radio telescope or even a small transmitter can always sent a signal toward ...

There are parameters from the data listed here There is a site with raw data for FRB 121102, another repeating FRB, but the data set is 400 TB. The first site has links and may take you to the site where the data is stored. There is a Wikipedia page with your specific FRB listed among others. The sources listed for 180916 may take you to the data site.

On the fast radio burst side of things: The FRB distribution is isotropic so far, which isn't surprising - you'd expect cosmological sources of this sort to be more or less everywhere in the sky. This means that you could point your telescope at random and still have a roughly equal chance of detecting one - albeit an extremely low chance. Fortunately, in ...

Further to Surya answer, yes ASKAP can and does detect FRBs in semi-realtime. The reporting to the outside world is far from realtime, unfortunately. In summary an incoherent sum all antennas is made (ie sum of the power) with coarse spectral resolution (1 MHz) and relatively short integration time (~1 millisec). This data is searched in realtime and FRB ...

I have recently learned (after some struggle similar to yours) that astropy is not the easiest way to deal with a fits file. Way better to use curvit. Have a look at the functions makecurve and curve. They are able to locate a light source in your file and to compute the intensity vs time. They will save a plot image and a data file on you PC with three ...

If your original file has a bunch of columns and you only want to keep two of them, you could try from astropy.table import Table data = Table.read('path/to/file.fits') column_names = ['time', 'intensity'] # or whatever the names of the columns you want to keep are data = data[column_names] data.write('path/to/new_file.fits')

This may be a partial answer depending on what you do or don't know how to do at the moment, and the level of accuracy you require. Feel free to add some feedback. If you'd like to use (or learn to use) Python then you can solve this problem trivially using Skyfield! It depends on the level of accuracy that you need. The time difference will be of the order ...

There is a tentative detection of a GRB simultaneously with an FRB, DeLaunay et al 2016. If it is true, it would mean that at least some FRBs have the same origin as some GRBs. Theoretically many possibilities were suggested before and after this tentative, detection. For now they all remain quite speculative, and more observations are required (and ...
