Research

Identifying OH Imposters

OH Megamasers (OHMs) are an astrophysical maser that often serve as a marker of merging galaxies. The signal of OHMs can be spoofed by a similar signal from HI 21cm spiral galaxies at different redshifts. I am searching for a proxy to sort these two populations from each other in support of the LADUMA survey on South Africa’s MeerKAT.

 

Past Research

I have had the privilege of exploring many fields in physics and astrophysics. Below is a small sample of the work I have done in the past.

In search of Inflation
(2016-2018)

Polarbear is a ground-based experiment searching for a small signal of polarization in the Cosmic Microwave Background (CMB) that would be the smoking gun for inflation. For Polarbear, I tested, characterized, and designed detectors that are deployed to the telescope to measure these small signals. (AAS 2018 Poster)

Solar Image Processing
(Summer 2015)

Understanding the Earth’s climate requires understanding the Sun. The Precision Solar Photometric Telescope (PSPT) located at the Mauna Loa Solar Observatory acquires images of the Sun to monitor the evolution of the solar surface. I processed raw images coming from the telescope to remove false features and artifacts and prepare them as a scientific package. (AGU 2015 Poster)

Undergraduate Work

As an undergraduate, I studied laser assisted electron scattering. Further, I worked in the machine shop on campus building pieces and machinery, including a milling machine and CNC. I also taught students how to use the equipment.

Public Outreach

Possibly the coolest thing about Astronomy is how exciting it is to share with the public. I’ve been able to do this in a few ways.

Currently, I am designing and teaching an after-school enrichment program for 4th and 5th graders in the Boulder Valley School District called Boulder Junior Astronauts. Each week, we '“visit” a new planet and perform hands on experiments to learn something new about each of the planets in our Solar System.

University of Colorado Boulder has something called Astronomy Day which is an open house in which the public can come into our planetarium and observatory for free and learn about astronomy. For the last two years, I have run a room dedicated to educating people about millimeter and radio astronomy by using Tesla coils, microwaves, and Jacob’s ladders.

A few other examples of outreach I’ve done are serving as a science fair judge, visiting elementary schools to demonstrate experiments, and hosting panels for high school students to ask graduate students questions.

Education

I have been involved with education at all levels from elementary schools (as seen in outreach) to undergraduates.

Mentoring students is my favorite way to one-on-one spread knowledge and teach something new to students. I’ve mentored two undergraduates since being in graduate school. The first in learning how to code and process telescope data and the second in building and assembling pieces for detector testing. In 2018, I mentored a high school student for his senior class project on Instrumentation in Cosmology.

In graduate school, I have graded or held open office hours for a few classes including Astrophysics 1 and 2 (undergraduate level) and Atomic and Molecular Processes (graduate level).

As an undergraduate, I was a teaching assistant for Physics 1, 2, and 3, Mathematical Methods in Physics, and Engineering Physics.

Diversity and Inclusivity

Making astronomy a more diverse and inclusive field is a goal that I share with many others. I run a group called Promoting an Inclusive Community in Astronomy (PICA) where we discuss these exact goals with regular meetings. Though we are largely a discussion group, we take action when needed. For example, we had an open conversation with campus advocates and lawyers about how the end of DACA (Deferred Action for Childhood Arrivals) will affect astronomy and how we can protect and support students or staff with DACA. We also strongly advocated for abolishing the Physics GRE requirement in the department due to the known biased nature of the exam and were able to change to optional for future applicants.

I have also served on many committees within the Astrophysical and Planetary Sciences department (APS) at University of Colorado Boulder that aim to make our department a better place. This includes:

  • Concerns Committee - which is dedicated to solving internal issues in the department

  • Exams Committee - a committee of students and faculty that make sure our comprehensive exams are fair

  • Faculty Search Committee - a committee in charge of hiring a time-domain astronomy faculty member

About

My name is Hayley Roberts and I am studying to be an Astrophysicist.

In 2016, I began my PhD in Astrophysics at University of Colorado Boulder. Before graduate school, I received my B.S. in Physics from Illinois Wesleyan University.

I am passionate about space but also inclusivity and diversity in the field.

Outside of research and outreach, I enjoy learning about data science and visualization.
