The MMM project
- What is Merger rate at high redshift?
- What is the Morphology of galaxies in the rest frames at high redshift?
- How does the Mass in stars build up in galaxies?
These are the questions behind the MMM project. To answer all these questions
we need deep (K_AB=25), high-resolution infrared data:
Gemini Adaptive Optics
We propose a deep, targeted imaging survey down to K_AB=25 with
Altair+NIRI. Twenty fields near bright guide stars will be selected in
each of the CFHT Legacy Deep fields.
In a subsequent proposal we will undertake AO spectroscopy using
Altair+NIFS of a subset of the objects to create a redshift survey
between 2 and 3 magnitudes deeper than any other K selected sample.
NICMOS Ultra Deep Field
To some extent, these science goals can be achieved in the currently
available NICMOS observation in the Ultra Deep Field. These
observations are smaller in area (factor of ~2) and lower resolution
(factor of ~3) the Gemini adapative optics observations. Also, they
only extend to the H band (1.6 um) and not the K (2.2 um). However,
they are slightly deeper and the data is already in hand.
