  1. 1 Summer course 2018 - A Random walk in astro-physics
  2. 2 The Interstellar Medium Lecture-03
  3. 3 The Interstellar Medium
  4. 4 Star cluster NGC 265
  5. 5 As we journey through the interstellar space, we will encounter spectacular gaseous nebula and remnants of supernovae.
  6. 6 The great nebula in Orion
  7. 7 The horse head nebula
  8. 8 Pillars of dust in the Eagle Nebula
  9. 9 Cassiopeia A, the expanding supernova remnant
  10. 10 X-ray image of the remnant of TYCHO's supernova of 1572
  11. 11 Discovery of 21 cm radiation from Hydrogen
  12. 12 Discovery of interstellar hydrogen was one of the greatest discoveries in the history of astronomy. It revolutionized astronomy
  13. 13 The "Doppler shifted frequencies" will be different for the three clouds
  14. 14 Modelling the distribution of neutral hydrogen in the Galaxy
  15. 15 Random motion of clouds superimposed on their systematic motion around the center of the Galaxy.
  16. 16 The distribution of the neutral hydrogen gas in the Milky Way.
  17. 17 Raisin pudding model of the Interstellar Medium
  18. 18 Interstellar Medium Molecular Gas
  19. 19 Molecular Spectra
  20. 20 Rotational spectrum: A rotating molecule will radiate only if it has a permanent electric dipole moment.
  21. 21 Spectral region of rotational transitions
  22. 22 Vibrational levels
  23. 23 Molecules in interstellar space
  24. 24 Giant Molecular Clouds
  25. 25 All or nothing
  26. 26 M 51 - Whirlpool Galaxy. Right is the visible image. The dark lanes trace the distribution of dust.
  27. 27 Distribution of molecular clouds is shown in blue
  28. 28 A star cluster in the Rosette Nebula. The wavelength of the recombination radiation will tell us about the composition of the gas.
  29. 29 Some 'compression wave' triggers a burst of star formation. A young star cluster is born.
  30. 30 Celestial Masers
  31. 31 The OH maser was the first celestial maser to be discovered in 1965.
  32. 32 Maser environment
