mma Flashcards
which messanger is caused by which process?
name mma’s?
em, cosmic rays, neutrino, gw
give an overview of what learned in mma?
gw170817: gw signal (mass)
x-ray
gamma ray
kilonova
example of each mma source?
em, cosmic, neutrino (sun)
gw (gw170817 ns merger)
gw produced by?
bh + ns merger
or
nsb merger
what are NS? mass? inner structure? how are they supported against gravitational collapse?
why study NS/ BH?
extreme densities
GR & nuclear physics lab
heavy element formation
how can study NS?
gw (merger)
x rays (poles)
how to info from multiple sources combine?
how gw produced?
acc of masses– disturbance in space time
what do gw observations measure?
f,
amp,
location in sky (based on arrival time from diff detectors)
can symmetric objects (not distorted) make gravitational waves?
how can combination of detectors help localization of signal in the sky?
possible mechanism(s) for GRB emission?
- magnetar
- neutrino anhilation
- acc of particles along string mag field lines
possible mechanism(s) for x ray emission in gw170817?
fallback accretion
