Instrument Use Policy

Introduction

MagAO-X is an experimental coronagraphic extreme adaptive optics system. It seeks to employ the latest cutting-edge technologies to demonstrate the highest possible contrast at the smallest possible inner working angles, to enable exoplanet, circumstellar disk, and other high contrast and/or high resolution astronomical observations.

MagAO-X is a PI instrument, still undergoing commissioning. Operation of MagAO-X is very complex, and requires the support of a large team both at the telescope and in the lab to prepare it for telescope observations. We welcome scientific proposals, for either astronomy observations or technical/instrumentation experiments, from Magellan Consortium members in collaboration with the MagAO-X team. Any such proposals must be approved by the MagAO-X PI prior to submission.

Collaborations

To use MagAO-X, you must first agree to offer co-authorship on any publications which include MagAO-X data to members of the MagAO-X team who have supported your observations. This will include researchers (including students, post-docs, and faculty) who have helped develop, implement, and test the various observing modes, algorithms, and technologies as implemented in MagAO-X, in addition to the specific team members at the telescope for your run. We will provide a list of co-author names and affiliations for any such MagAO-X publications when requested.

To propose to use MagAO-X in collaboration with the team, please send the following to the MagAO-X PI (Jared Males, jrmales@arizona.edu) at least 72 hrs prior to your institution’s deadline:

  • The project title.

  • A complete list of researchers outside the MagAO-X team collaborating on the project.

  • An abstract providing basic scientific and technical information about the project.

  • List of targets, with RA and Dec.

This information will be used by the MagAO-X team to assess technical feasibility, and ensure that there are no conflicts between various users of MagAO-X. This latter need is crucial given the limited telescope time available and the relatively small number of targets in our performance envelopes.

The H-alpha Proto-Planet Survey

Currently, our team’s key astronomy science project is the MagAO-X H-alpha Protoplanet Survey, MaXProtoPlanetS. Lead by Co-PI Laird Close, this is a survey of nearby young stars to look for planetary mass companions using the H-alpha accretion signature. Collaborations within the context of this survey are welcome, contact Laird Close (lclose@arizona.edu) to discuss.

This project is one of the key performance drivers of the first phase of MagAO-X, and one of our main motivations for developing this instrument. As such, many of the well-known targets are reserved as part of this survey. Below is the current list of reserved targets, which will be updated periodically as we revise selection criteria, and before the proposal cycle for planned runs. (The below list is currently only for 2020B).

We encourage proposals to observe H-alpha targets not on our list, e.g. new proprietary targets, with MagAO-X and will work (discreetly when necessary) to support your observations.
