\section{ Neutrino Astronomy }
\begin{frame}{ Neutrino Astronomy: History }
	\begin{itemize}
		\item First observation of neutrino in 1956
		\item Deep Underwater Muon and Neutrino Detector, Hawaii (1990)
			failed, but proof of concept for ANTARES, KM3NeT

		\item Antarctic Muon and Neutrino Detector Array (, now part of IceCube)
	\end{itemize}

\end{frame}
\begin{frame}{ Neutrino Astronomy: Basics }
			\begin{itemize}
				\item Neutrino interacts in atmosphere, ice or water
				\item Charged particle gets into the ice or water and emit Cherenkov photons
				\item Cherenkov photons detected by DOMs in the matter
			\end{itemize}

\end{frame}
\begin{frame}{ Neutrino Astronomy: Production }
	Neutrinos produced in sources and CR interactions
	\begin{itemize}
	\item Main CR interactions: 	
		\begin{itemize}
			\item $ p + \gamma_{bg} \to p + \pi^0 \to p + \gamma + \gamma $
			\item $	p + \gamma_{bg} \to n + \pi^+ \to n + \mu^ + \nu_\mu \to n + \nu_\mu + e^ + \bar{\nu_\mu} + \nu_e $
		\end{itemize}
	\end{itemize}

\begin{frame}{IceCube observatory}

\begin{frame}{IceCube observatory}
	Divided into three parts:
	\begin{itemize}
		\item IceTop: detects CR airshower above IceCube
		\item IceCube: the main detector for $E_\nu > 100$ GeV
		\item DeepCore: sensitive for $E_\nu \raise.17ex\hbox{$\scriptstyle\sim$} 10$ GeV due to tight spacing
	\end{itemize}
\end{frame}

\subsection{Event Detection and Background}
\begin{frame}{Event Detection}
	Event selection and simulation needed to identify particles.\\
	IceTop and outer region of IceCube are veto regions.
