Untangling a Complex Young Stellar System

The top panel shows the spectrum of KH 15D during its "bright" phase, when the amount of direct starlight was greatest. The middle spectrum ("intermediate" phase) was taken when star B was just below the edge of the ring. Both spectra in the bottom panel were obtained during "faint" phases from two different cycles, when both stars were near periastron and the contribution from starlight was minimized.

False-color image of SPT-CL J0546–5345 at z = 1:067. Gemini GeMS/GSAOI Ks (this work) = red, HST ACS F814W = green, HST ACS F606W = blue. The red polygon shows the approximate sky coverage of the GSAOI pointings. PSF stars are indicated by white circles. The star near the top of the image with two circles is a binary star. The inset at lower left is a zoom-in of the cluster core.

Instrument Upgrades: Teams seeking collaboration

Gemini encourages collaborations and will provide a forum for those seeking additional partners to complete a team for this work. Groups interested in Instrument Upgrades who may lack the expertise needed to complete the work should submit a notice of intent and use this forum to find additional partners for the work.


Gemini data reduction software on MacOS 10.12 (Sierra)

We currently anticipate completing integration and testing of our data reduction software with AstroConda in November this year. In the meantime, our recommended platform is still Ureka 1.5.1 or 1.5.2.
