Simulation

We can bring together the detector and source modelling to calculate the expected number of neutrino events and run simulations.

Defining a source and detector model

from icecube_tools.detector.r2021 import R2021IRF
from icecube_tools.utils.data import SimEvents
[3]:
# Define detector (see detector model notebook for more info)
aeff = EffectiveArea.from_dataset("20210126", "IC86_II")
irf = R2021IRF.from_period("IC86_II")
# IceCube expects an instance of EffectiveAerea, AngularResolution and
# EnergyResolution, optionally the period (here IC86_I)
# R2021IRF inherits from AngularResolution and EnergyResolution
# just to be able to be used as both
detector = IceCube(aeff, irf, irf, "IC86_II")
[4]:
# Define simple sources (see source model notebook for more info)
diff_flux_norm = 3e-21  # Flux normalisation in units of GeV^-1 cm^-2 s^-1 sr^-1
point_flux_norm = 5e-19  # Flux normalisation in units of GeV^-1 cm^-2 s^-1
norm_energy = 1e5  # Energy of normalisation in units of GeV
min_energy = 1e2  # GeV
max_energy = 1e8  # GeV

diff_power_law = PowerLawFlux(diff_flux_norm, norm_energy, 3.7, min_energy, max_energy)
diff_source = DiffuseSource(diff_power_law, z=0.0)

point_power_law = PowerLawFlux(
    point_flux_norm, norm_energy, 2.5, min_energy, max_energy
)
point_source = PointSource(point_power_law, z=0.0, coord=(np.pi, np.deg2rad(30)))
sources = [diff_source, point_source]

Expected number of neutrino events

Sometimes we just want to predict the number of events from sources in a detector without specifying all detector properties or running a simulation. We can do this with the NeutrinoCalculator. For this, we just need a source list and an effective area.

[5]:
from icecube_tools.neutrino_calculator import NeutrinoCalculator, PhiSolver
[6]:
nu_calc = NeutrinoCalculator(sources, aeff)
nu_calc(
    time=1,  # years
    min_energy=min_energy,
    max_energy=max_energy,  # energy range
    min_cosz=-1,
    max_cosz=1,
)  # cos(zenith) range
[6]:
[185.18577999134666, 24.51408397397894]

The calculator returns a list of expected neutrino event numbers, one for each source.

We may also want to do the inverse, and find the PointSource flux normalisation corresponding to an expected number of events. For this there is the PhiSolver class.

[7]:
phi_solver = PhiSolver(
    aeff, norm_energy, min_energy, max_energy, time=1, min_cosz=-1, max_cosz=1
)
phi_norm = phi_solver(Nnu=15, dec=-30, index=2.0)  # degrees  # spectral index
phi_norm  # GeV^-1 cm^-2 s^-1
/opt/hostedtoolcache/Python/3.9.20/x64/lib/python3.9/site-packages/icecube_tools/neutrino_calculator.py:294: RuntimeWarning: The iteration is not making good progress, as measured by the
  improvement from the last ten iterations.
  phi_norm = fsolve(self._solve_for_phi, x0=guess, args=(Nnu, dec, index))[0]

Set up and run simulation

[8]:
from icecube_tools.simulator import Simulator, TimeDependentSimulator
[9]:
# Set up simulation
simulator = Simulator(sources, detector, "IC86_II")
simulator.time = 1  # year

# Run simulation
simulator.run(show_progress=True, seed=42)
Sampling: 100%|██████████| 204/204 [00:00<00:00, 232.58it/s]

This way, the simulator calculates the expected number of neutrinos from these sources given the observation period, effective area and relevant source properties. We note that we could also run a simulation for a fixed number of neutrinos if we want, simply by passing the optional argument N to simulator.run().

Time dependent simulation

We can simulate an observation campaign spanning multiple data periods of IceCube through a “meta class” TimeDependentSimulator:

[18]:
tsim = TimeDependentSimulator(["IC86_I", "IC86_II"], sources)
/opt/hostedtoolcache/Python/3.9.20/x64/lib/python3.9/site-packages/icecube_tools/detector/r2021.py:89: RuntimeWarning: divide by zero encountered in log10
  self.dataset[:, 6:-1] = np.log10(self.dataset[:, 6:-1])
Empty true energy bins at: [(0, 0), (1, 0)]
Need to set simulation times, defaults to 1 year each.

We need to set simulation times for all periods. Since for past periods the simulation time shouldn’t be larger than the actual observation time (that is time span - down time of the detector) we need to take care, or rather, we let the class Uptime take care:

[19]:
from icecube_tools.utils.data import Uptime

It lets us calculate the actual observation time through, e.g. IC86_II, vs the time covered:

[20]:
uptime = Uptime("IC86_I", "IC86_II")
uptime._time_obs("IC86_II"), uptime.time_span()["IC86_II"]
[20]:
(0.9089039325939252, 1.0157235341273203)

We can further define a start and end time of an observation and let it calculate the observation time in each period. Viable possible options are - start and end time in MJD - start time in MJD and duration in years - end time in MJD and duration in years

If the start time is before the earliest period (IC_40), the start time will be set to the earliest possible date.

If the end time is past the last period (IC86_II), then we get an according message and simulate into the future.

We can of course bypass this time setting and operate directly on the instances of Simulator, for example if we’d want to build up large statistics for subsequent likelihood analysis.

[21]:
times = uptime.find_obs_time(start=55869, duration=3)
times
[21]:
{'IC86_I': 0.4798785512080253, 'IC86_II': 2.425230588331747}

The returned dictionary can be used to set the simulation times for an instance of TimeDependentSimulator:

[22]:
tsim.time = times

The simulation is started by calling run(), results can be saved by save(file_prefix), with the filename being {file_prefix}_{p}.h5 with period p.
