MSAM/TopHat is a collaboration working on a series of experiments to measure the medium-scale anisotropy of the cosmic microwave background radiation (CMBR). This extremely faint radiation from the birth of the Universe is detectable in the radio and microwave parts of the electromagnetic spectrum. The small variations in the intensity of this faint signal (about 1 part in 100000) from different parts of the sky tell us many fundamental things about the Universe, such as its size and mass. You can:

• Read a brochure about our research program.
  
  
• View a brief history of our program.
  
  
• Read a brief tutorial about CMBR.
  
  
• Read about some of the new technologies we are developing.
  
  
• Look at our images.
  
  
• View an annotated bibliography of MSAM/TopHat related publications and retrieve these documents.
  
  
• Get the publicly released data from our flights.
  
  
• Find out how to work with us.
  
  
• Give us feedback through our guestbook.
