Smallest Known Galaxy with a Supermassive Black Hole

Figure 1. Stellar Kinematic Maps of M60-UCD1 showing clear rotation and a dispersion peak. Panels a and b show the measured radial velocities (bulk motions towards & away from us) and velocity dispersions (random motions) of the stars in M60-UCD1 with typical errors of 6 km/s. Black contours show isophotes in the K band stellar continuum.

Bias Images (N and S)

Example bias images are available for the following instrument/detector combinations:


Gemini Frontier Field: First Data Now Available

Figure 1. Part of MACS J0416-2403 seen by GSAOI. The average angular resolution is about 80 milliarcseconds, the full field-of-view of the data released is nearly twice as large as shown here.

GMMPS for Hamamatsu CCDs available

The latest version of the Gemini MOS Mask Preparation Software (GMMPS 0.4.1) is now available. Please see the GMMPS web page for more information and download links.


Calibrations for GNIRS consist of the following measurements.

GMOS-S Gain and Read Noise Values

The table below gives gain/read-noise values for the current GMOS Hamamatsu CCDs measured in September 2014.

Note: GMOS South data obtained before May 19, 2014 should use the previous gain/read-noise values.
