2. Who  am  I?                                Astrophysicist                                                                    &                                          Aspiring  Data  Scientist PostDoc:  Caltech/JPL,  Astrophysics   PhD:  Leiden  University,  Observatory   MSc:  Groningen  University,  Astronomy   BSc:  Ankara  University,  Astronomy   BCert:  University  College  London -­‐ Star  formation   -­‐ Astrochemistry     -­‐ Astroinformatics   -­‐ Big  Data
3. 3 •Stars...  we  are  stardust... •Where  do  they  come  from?   •How  did  they  form? •How  many  of  them,  is  there  an  end? Questions,  Questions,  Questions
5. Infrared  Cameras Measuring  the   temperature  of  the   region
6. Different  cameras,  different  images Optical Infrared
7. Cloud                        Stars

18. O2 Abundance  of  Oxygen Yıldız  et  al. Theoretical Observed 7x10-­‐5 6x10-­‐9 in  Star  Formation NASA Press Release, 2013
19. Astroinformatics Galileo’s  first   observations  of   Jupiter’s  moons Astronomers  are   native  data  collectors
20. ALMA  Interferometry Atacama/Chile   66  x  12m  dishes   Correlator  Computer   500  GB  data/day
21. Interferometry
22. VLBI  -­‐  Very  Large  Baseline  Interferometer
23. Square  Kilometer  Array South Africa and Australia Construc)on  begins  in 2018 ends in 2023 Total cost $2 billion
24. Square  Kilometer  Array SKA  low   130.000  antenna SKA  high   100  dishes
25. Square  Kilometer  Array The  data  collected  by  the  SKA  in  a  single  day   would  take  nearly  two  million  years  to  playback   on  an  ipod.   -­‐  Full  operation:  700  TB  data/second!!! The  SKA  will  be  so  sensitive  that  it  will  be   able  to  detect  an  airport  radar  on  a  planet   tens  of  light  years  away. The  SKA  central  computer  will  have  the   processing  power  of  about  one  hundred   million  PCs.
26. Square  Kilometer  Array The  dishes  of  the  SKA  will  produce  10   times  the  global  internet  traffic. The  SKA  will  use  enough  optical   fibre  to  wrap  twice  around  the  Earth! The  aperture  arrays  in  the  SKA   could  produce  more  than  100  times   the  global  internet  traffic.
27. -­‐  Temperatures  above  2.7  Kelvin   -­‐  Medical  Imaging        -­‐  Better  than  X-­‐ray  for  detecting   cancer  cells So,  what  about  real  life? -­‐  3D  teeth  imaging   -­‐  THz  Tomography   -­‐  Body  Scanner  at  the  airports
28. -­‐  Temperatures  above  2.7  Kelvin   -­‐  Medical  Imaging        -­‐  Better  than  X-­‐ray  for  detecting   cancer  cells So,  what  about  real  life? -­‐  3D  teeth  imaging   -­‐  THz  Tomography   -­‐  Body  Scanner  at  the  airports
29. So,  what  about  real  life? -­‐ Camera  for  drones,  not  affected   from  cloud  or  dark   -­‐ High  Altitude   Telecommunication,  especially   where  the  water  vapor   absorbs  the  signal;  e.g.,   airplanes  to  satellites   -­‐ Camera  for  airplanes  to  see   beyond  foggy  or  cloudy   conditions
