3D galactic dust Temperature map

Note: the data for the map is available upon email request, with the number of distance bins, nside parameter, customizable; we are working on the choosing the best way to share it online.

Researchers have long used dust emission to map dust in 2D, and in recent years starlight reddening has been used to map dust in 3D. However, the technique of combining 3D information from reddening with emission data is still in incipient stage. In this work,  I combined these two datasets to create the first large scale 3D galatic dust temperature map. You can see a video of the result below:  3D visualizations of the 27′ map of the temperature of galactic dust and its density. The intensity is proportional to the density, and the RGB variation is temperature dependent. Blue is sensitive to the shortest wavelength (hotter dust, ~20K), red to longer wavelengths (cold dust), and green to intermediate values. The perspective shown here features a screenshot the camera placement doing a 25-pc loop around the Sun, looking in the galactic plane towards the anti-center (180 galactic longitude), towards the Orion, Taurus, Perseus, and California clouds. 

Epoch of Reionization

During my time at MIT, my research focused on building an interferometer telescope, as part of the research group lead by MIT Professor Max Tegmark. I was directly responsible with creating the real-time cross-correlator data processing pipeline, programming FPGAs on ROACH boards, for a 64 antenna design. We deployed the telescope which took data successfully in Maine, validating the design.

List of publications resulting from this work:

During my PhD, I looked at interstellar dust and its impact on Cosmic Microwave Background experiments. I worked in the research group of Harvard Professor Douglas P. Finkbeiner.

I completed a significant new study of interstellar dust grains, their variations in size and composition, and the effects on interstellar extinction.

Building on that work, I studied contribution from interstellar and non-galactic dust on the detection of the spectral distortions of the cosmic microwave background.

https://arxiv.org/abs/2010.06589

Finally, I created the first 3D map of the temperature of the interstellar medium dust. The work is published as the third chapter of my thesis and is now in pre-print as an article.

Currently, I am working as a Postdoctoral Scholar at UCLA in Professor Tommaso Treu’s research group. I am looking at using strong lensing to put constraints on dark matter models. For certain classes of dark matter theories, I am trying to figure out what would be the growth of structure, and what observables they would have, leading to comparisons with data.

DARK MATTER and GRAVITATIONAL STRONG LENSING

After my PhD, I spent a year as a Postdoctoral Scholar at UCLA in Professor Tommaso Treu’s research group. I am looking at using strong lensing to put constraints on dark matter models. For certain classes of dark matter theories, I am trying to figure out what would be the growth of structure, and what observables they would have, leading to comparisons with data.
