North Carolina Astronomers' Meeting (NCAM)

NCAM 2021

Virtual Meeting, Saturday, 25 Sept.
Featured Speaker: Shep Doeleman, Harvard/CfA/EHT

NCAM is an annual technical meeting that seeks to bring members of the NC professional astronomy community together to network and share research. The meeting usually draws 50-75 attendees from institutions around North Carolina and surrounding states. For the past two decades, NCAM has been held annually in late September or early October, and includes a plenary presentation from an invited researcher, short oral sessions scheduled throughout the day, and space for research posters.  We especially encourage presentations of student research. The meeting also usually includes two special sessions:  the annual business meeting of the NC Section of the International Dark-sky Association, and a Center for Astronomy Education Regional Teaching Exchange.

Because of the high COVID-19 Delta variant caseload, the 2021 edition of NCAM will be held virtually, with assistance from Guilford College.

Morning Plenary Lecture: Sheperd S. Doeleman, Harvard/CfA/EHT

Presentation title TBA

About the Speaker: Dr. Sheperd S. Doeleman, the founding director of the Event Horizon Telescope project, is a Harvard Senior Research Fellow and Smithsonian Astrophysicist at the Harvard-Smithsonian Center for Astrophysics.  His research focuses on studying super massive black holes with sufficient resolution to directly observe the event horizon. To do this our group assembles global networks of telescopes that observe at mm wavelengths to create an Earth-size virtual telescope using the technique of Very Long Baseline Interferometry (VLBI). We target SgrA*, the 4 million solar mass black hole at the center of the Milky Way, and M87, a giant elliptical galaxy for this work. Both of these objects present to us the largest apparent event horizons in the Universe, and both can be resolved by (sub)mm VLBI arrays. We call this project The Event Horizon Telescope (EHT).

Dr. Doeleman will also give a free public lecture at GTCC the evening before NCAM.

Meeting Registration

NCAM is free and open to professional astronomers and astronomy/physics students/faculty from North Carolina and surrounding states. Note: NCAM is not a public/amateur astronomy event – we host one of those in the spring (TriStar).

We would like to get a reasonably accurate head count for the meeting, so please complete the registration form or contact Tom English beforehand if you are planning on coming Registrations for presentations should be completed by Tuesday, 21 Sept. If you plan to participate but NOT to present, we would still like for you to register beforehand – you can do this until Friday, 24 Sept.

Abstract Submission

If you would like to present an oral or display presentation at the NCAM meeting, please complete the registration form by Wednesday, 21 Sept.

Display Presentations

Posters, submitted as pdf files, will be linked on the meeting website and assigned virtual breakout rooms for special sessions during the meeting. 

Oral Presentations

The proposed plan is for standard oral presentations to be 10 minutes including Q&A, though this could change, depending on the number of submissions.

After you submit the registration form, you should receive confirmation of receipt within a day of submission; if not, call or e-mail Tom English (336-334-4822, Ext. 50023) to verify.

Special Sessions

  • The annual business meeting of the North Carolina Section of the International Dark Sky Association will be held during the lunch break. (If you have questions about NCIDA or ideas for discussion at the meeting, contact Dan Caton (Appalachian State University Dark Sky Observatory).
  • NCAM acts as an annual site for a Regional ASTRO101 Teaching Exchange – a discussion/presentation session will be held during the afternoon. Anyone who currently teaches introductory college astronomy, or who expects to teach in the future, is encouraged to attend. (If you have ideas for the discussion, contact Tom English at GTCC.)
