Below I list some highlights of recent news that is connected in
some way with me or my work.
- Swift X-ray point source catalogue available. The
1SXPS catalogue of >150,000 point
sources is now available. The paper describing it (Evans et al. 2014)
is available on arXiv.
- Swift discovers a powerful, nearby GRB which you can
read about on the BBC
- Live GRB Catalogue online - The GRB analysis contained in
XRT GRB Catalogue is now automatically carried out for each new GRB (once it is 24 hours old) and
the results are posted online.
- New Swift website launched - After a lot of work, our new website
has been released. As well as a new design, the underlying system is much more efficient, so the on-demand jobs
and GRB processing should run more quickly
- Burst Analyser released - My recent project, the Swift Burst Analyser is now
online. A paper describing it is on ADS: Evans et al.,
2010, MNRAS, 402, 46
- Swift_Phil on Twitter - I am providing a Twitter feed on a "professional" basis,
that is in my role as a Swift scientist. I'm Swift_Phil on Twitter
and also have a supporting website.
- GK Per paper in outburst - GK Per has gone back into outburst. Various observing campaigns are watching
it. See ATEL 2466 for more.
- GK Per paper published - My paper on the 2006 Dwarf Nova outburs of
GK Perseii has been published: MNRAS, 399, 1167.
- New p-distribution paper - Peter Curran has led a paper along with myself,
Mat Page, Max de Pasquale and Alexander van der Horst, investigating whether
we can tie down the distribution of p —
the election energy distribution index — using the late-time
XRT spectra. The answer is yes! For more details, see
- XRT catalogue published - It's taken long enough, but finally the paper
has made it through the typesetting etc stage and into the journal. MNRAS, 397, 1177
- GK Per paper accepeted - My latest lead-author paper,
presenting and discussing multi-wavelength data on the 2006 Dwarf Nova outburst
of GK Per, has been accepted by MNRAS. It's on arXiv as 0907.1407.
- Most distance object ever observed seen by Swift! - GRB
090423 has a spectrscopic redshift somewhere around 7.6 or 8.2 (see GCN Circ.
9216, 9129), making it the most
distant object with a spectoscopic redshift. To see how that fits in with
other GRBs, see my Cumulative plot of GRB redshifts
for Swift GRBs.
- XRT autoprocessing and catalogue paper accepted - data on VO - The arXiv entry
has been updated, and the data are now available through the VO: ivo://uk.ac.le.star.swift/dsa_grb_aux/SwiftXRTGRBCat
- Up to second in Google! - OK, OK, so it's a bit egotistical, but if you do a Google for
"Phil Evans" this site is now the second hit. Just got to get rid of that wedding photographer....
- Swift to feature in the Science museum. In July,
the Science museum are launching a new exhibition to celebrate the
400th anniversary of the telescope. Swift is due to feature there, along
with photos and interviews with Kim and myself.
- XRT autoprocessing and catalogue paper on arXiv. This paper (arXiv 0812.3662) - representing
most of my work since joining the Swift project - details the algorithm
used to create XRT
spectra, the changes to the enhanced positions since
al. (2007), and a few updates to the light curves since Evans et
al. (2007), as well as introducing the XRT products generator (below). It also presents
a catalogue of results produced from these tools for the 318 GRBs detected by XRT up to GRB 080723B.
- Swift XRT product generator online. You can now create XRT products
(enhanced position, light curve, spectrum) for any object detected by the
- Time-slice GRB spectra. The XRT GRB spectra have a new
feature: you can now create time-resolved spectra. Follow the link on the
results page for the GRB in question.
- XRT GRB products web site launched. A number of times recently I've thought
that there should be a single page per burst linking the various XRFT automatic products, rather
than having three separate indices. So, now, there is.
- IGR J08408 paper in press. Earlier this year (2008) Swift triggered
on a series of outbursts from the Supergiant Fast X-ray Transient (SFXT) known as
IGR J08408-4503. Our paper led by
Pat Romano, has been accepted for publication in MNRAS.
- A day in the life video. Brady Haran, a BBC journalist
recently followed Rhaana and me
to produce a "day in the life" video, partly aimed at encouraging
young people into science. The video is online here.
- Swift sees most distant burst. On 2008 Sep 13th, at 7:07am BST,
Swift detected a GRB at a redshift of 6.7 (see GCN Circ.
the NASA press release.) It was about 120,000,000,000,000,000,000,000 km away, the energy had been
travelling for 12,826,000,000 years ago.
- Brightest GRB seen by Swift. On 2008 March 19th, Swift
detected a GRB. This was half way across the universe, but bright enough
to be seen by the naked eye! (It peaked at mag 5). Read about it
in this Nature article.
