OTHER: Python Example

[b0g]

Python example
using astropy and other Python modules to plot "confirmed" FRB Fast Radio Bursts from Python code on a galactic coordinates plot.

The sources from the milky way should be around the horiz. 0° line. which is normal as most if not all comes from outer space.

Note 2 bursts from the galactic North pole.

work in progress...

I solved it something fierce!

From the editors:

Welcome to the FRB community newsletter. Our goal is to select and summarize recent results relevant to FRB researchers, both observational and theoretical, as well as to provide a curated selection of other relevant scientific news items, conferences, and more. We will aim to be:

timely and topical,
brief,
and archival,

such that the newsletter provides a monthly snapshot summary of the state of the field for the duration of this project.

We welcome your feedback, opinions, suggestions for items to post, news tips, etc.
- Emily Petroff and Shami Chatterjee, editors.

General news

Editors' note. This issue includes items from the first nine months of 2019. We anticipate future issues will be much shorter.
The FRBCAT VOEvent Broker is live. Interested parties can now subscribe to the FRBCAT Comet broker to receive VOEvents. Those interested in sending VOEvents via the FRBCAT broker or receiving broadcasted events should follow the instructions at the FRB_VOEvent github page.

FRB 121102 has been active again - or at least, has had several redetections, including at the Five-hundred-meter Aperture Spherical radio Telescope (FAST; ATel 13064), the Haoping 40-m telescope (ATel 13090), and MeerKAT (ATel 13098), among others. There are coeval upper limits from INTEGRAL at X-rays (ATel 13073) and UKIRT in the NIR (ATel 13075).
ASKAP has announced two FRB detections in the past few months: FRB 190711 (ATel 12922) and FRB 190714 (ATel 12940).
UMOST has reported the detection of FRB 190806 (ATel 12995).
CHIME has redetected the ASKAP FRB 171019 (ATel 13013); this FRB has now been detected at ASKAP (1.1-1.4 GHz), Green Bank (0.7-0.9 GHz; Kumar et al. above), and CHIME (0.6-0.8 GHz).
The MWA (139-170 MHz) shadowed the UTMOST detection of FRB 190806 reported earlier this year (see above) and reports upper limits on low frequency radio emission from this source (ATel 13121).

Upcoming meetings and conferences

FRB2020: Registration is now open for FRB2020 to be held in Khao Lak, Thailand. This meeting will aim to cover all aspects of FRB science and is limited to ~150 participants. Please see the meeting webpage for more details.

NB: these bursts are 3.000.000.000 light years away, or mostly ever more

this was the time our ancestors were stil sea scum.

those url links did not transfer, so here some... I add some later

I warped up data manipulation, visuals, learning python code, and source document conversion and lots of other tools...
http://vanoproy.be/python/FRB.html
don't shoot me cos the context is still poor, it's the visuals and conversion what's count for me
the rest can be added or read by links, which i 'll add..

And to understand the Aitoff projection: it only displays 1 side of the globe, so 360° get to 180° to fit into this display. you can't look behind it, or can you?
It is based on galactic coordinates which roughly means the plane of the orbit of the sun vs the polar star as 90° North.
