3
Large Magellanic Cloud, 1987 (51.4 kparsec) SN 1987a after before 2006 Hubble
4
Precursor of Superkamiokande H2OH2O
5
8 more events in IMB
7
Crab, 1054 About 1 SN every 30 years in our galaxy Einstein satellite (X)
10
Where does the acceleration take place? Cosmic rays
11
Look for the neutrals, not deflected in B fields, to identify, the sites of acceleration HE gamma and neutrino astronomy : created by synchrotronstrahlung, decay from decay: or very high energy charged particles Candidates: Fermi (SN remnants…) AGN, pulsars, …
12
From a presentation by: Paul Mantsch Auger Project Manger Building the Pierre Auger Observatory (Argentina)
13
Adventures in Cosmic Ray Physics
14
The Design
15
The Observatory Plan Surface Array 1600 detector stations 1.5 km spacing 3000 km 2 Fluorescence Detectors 4 Telescope enclosures 6 Telescopes per enclosure 24 Telescopes total
16
The Surface Array Detector Station Communications antenna Electronics enclosure 3 – nine inch photomultiplier tubes Solar panels Plastic tank with 12 tons of water Battery box GPS antenna
19
EGRET on Compton Gamma Ray Observatory (NASA) Galactic view
21
Active Galactic Nucleus (AGN) Matter accreting on supermassive black hole at center of galaxy
22
Gamma ray burst (GRB) must be « small » size sources
23
Microquasar: binary systems with a black hole
24
Ground based: look for electromagnetic shower induced in the upper atmosphere, measure Cerenkov light E>10 GeV HESS in Namibia (others: MAGIC in Mallorca, future (CTA))
25
shower hadron shower
26
HESS, stereoscopic view
29
Look for upward going muons
30
Neutrino astronomy principles
32
Antares Mediterranean, off Toulon, 3000 m deep, 0.1 km 2 Cerenkov light
34
t height Downward going muon
35
Antares, 0.1 km 2 at the bottom of the Mediterreanean (3000 m deep), Starting to take data But: needs 1 km 3 !!!
