A GIANT SEGMENTED MIRROR TELESCOPE: SYNERGY WITH JWST

What can JWST resolve?

A Jansky is 1e-26 W / m2-Hz. The Hz bandwidth can be estimated from the wavelength and wavelength window: Hz = c Δλ / λ2 . A parsec is

Two pixels needed for Nyquist deconvolution of point spread function. 0.11 arcsecond (as) pixels means 0.22 as minimum for estimating size (more is better) A 100 AU round shell is 0.22 as across at 450 pc. The galactic disk is 300 pc thick, G stars

What SOFIA can resolve?

The power of a 60K 3.86e26 W black body emitter between 35.5 μm and 38.5 μm is about 1.7e25 W.

Using the 37 μm dichroic filter, 3.5 μm wide, 900 second exposure, the bandwidth is 766 GHz. The power sensitivity is 0.42 Jy * 766 GHz or 3.22 e-15 W/m2.

4πR2 = 1.7e25 W / 3.22 e-15 W/m2 = 5.28e39 m2, R = 2.05e19 m. A parsec is 3.0857e16 meters, so R = 660 pc.
