Main Point: introduction of development of a new theory to understand quasar from scientists at Harvard CfA by studying Q0957+561 through microlensing
Key Structure:
Part I: introduction of quasar and Q0957+561 (the main object discussed in the article)
- definition of quasar: bright center of galaxies
- challenges faced by researchers to study quasar
- background of Q0957 & how does microlensing helps to to observe quasar
*hypo (mentioned for the first time) not blackhole but internal magnetic fields that run through the central object
Part II: specific findings and how they support the further development of the hypo
- evidence: 1) jets location, 2) internal part is wiped out, and 3) edge of the disk is bright, 4) cone structure
- best explained by the theory: internal magnetic field through the central object (new theory and different from what was previously believed)
Part III: additional details about the theory:
- Name: MECOs
- physical properties of MECO: dipole |
