The ability to represent scientific data and concepts visually is becoming increasingly important due to the unprecedented exponential growth of computational power during the present digital age....
The Dust Emissivity Spectral Index in the Starless Core TMC-1C (2009)
Schnee, Scott, Enoch, Melissa, Noriega-Crespo, Alberto, Sayers, Jack, Terebey, Susan, Caselli, Paola, ...
In this paper we present a dust emission map of the starless core TMC-1C taken at 2100 microns. Along with maps at 160, 450, 850 and 1200 microns, we study the dust emissivity spectral index from the...
Anchoring Magnetic Field in Turbulent Molecular Clouds (2009)
Li, Hua-bai, Dowell, C. Darren, Goodman, Alyssa, Hildebrand, Roger, Novak, Giles
One of the key problems in star formation research is to determine the role of magnetic fields. Starting from the atomic inter-cloud medium (ICM) which has density nH ~ 1 per cubic cm, gas must...

Abstract. The Perseus molecular cloud and its surroundings contain several regions of active or recent star formation lying within about 300 pc of the Sun (see Figure 1). Roughly a dozen OB and over...
Bridging the Gap Between Stars and Planets: The Formation and Early Evolution of Brown Dwarfs (2009)
Mohanty, Subhanjoy, Burgasser, Adam, Chabrier, Gilles, Padoan, Paolo, Hennebelle, Patrick, Pascucci, Ilaria, ...
This White Paper, submitted to the National Academy of Sciences' Astro2010 Decadal Review Committee, focuses on 2 central themes in the study of young brown dwarfs -- their formation mechanism and...
Application of Medical Imaging Software to 3D Visualization of Astronomical Data (2006)
Borkin, Michelle, Goodman, Alyssa, Halle, Michael, Alan, Douglas
The AstroMed project at Harvard University's Initiative in Innovative Computing (IIC) is working on improved visualization and data sharing solutions applicable to the fields of both astronomy and...
Visualization of Astronomical Data (2006)
Michelle Borkin, Alyssa Goodman, Michael Halle, Douglas Alan
Innovative Computing (IIC) is working on improved visualization and data sharing solutions applicable to the fields of both astronomy and medicine. The current focus is on the application of medical...
Padoan, Paolo, Goodman, Alyssa, Juvela, Mika
We compute the spectral correlation function (SCF) of 13CO J=1--0 maps of molecular cloud complexes. The SCF is a power law over approximately an order of magnitude in spatial separation in every...
Theoretical Models of Polarized Dust Emission from Protostellar Cores (2001)
Padoan, Paolo, Goodman, Alyssa, Draine, Bruce, Juvela, Mika, Nordlund, AAke, Rognvaldsson, Ornolfur Einar
We model the polarized thermal dust emission from protostellar cores that are assembled by super-sonic turbulent flows in molecular clouds. Self-gravitating cores are selected from a three...
A New Method to Measure and Map the Gas Scale-Height of Disk Galaxies (2001)
Padoan, Paolo, Kim, Sungeun, Goodman, Alyssa
We propose a new method to measure and map the gas scale height of nearby disk galaxies. This method is applied successfully to the Australia Telescope Compact Array interferometric HI survey of the...
Carol Lonsdale NASA Infrared Processing and Analysis Center (2001)
Science Foundation, Paul Messina, Alex Szalay, Alyssa Goodman, Stephen Kent Fermilab, Tom Mcglynn Gsfc/heasarc/usra, ...
astronomical surveys to produce terabytes of images and catalogs. These datasets will cover the sky in different wavebands, from gamma-and X-rays, optical, infrared, through to radio. In a few years...
Turbulent Fragmentation and the Initial Conditions for Star Formation (2000)
Padoan, Paolo, Nordlund, AAke, Rognvaldsson, Ornolfur Einar, Goodman, Alyssa
Super-sonic turbulence fragments molecular clouds (MC) into a very complex density field with density contrasts of several orders of magnitude. A fraction of the gas is locked into dense and...
