Reference excerpt

Laura B. Newburgh is an American experimental cosmologist and associate professor of physics at Yale University, where she is a member of the Wright Laboratory and the Department of Astronomy. She builds instruments for radio telescopes and CMB telescopes to probe dark energy, dark matter, neutrino mass, and cosmic inflation. She is a member of the Canadian Hydrogen Intensity Mapping Experiment (CHIME), the Hydrogen Intensity Real-time Analysis eXperiment (HIRAX), the Simons Observatory, and CMB-S4.

Education and career Newburgh received her Ph.D. in physics from Columbia University in 2010, where she worked on the Q/U Imaging ExperimenT (QUIET), a ground-based CMB polarization experiment designed to measure the B-mode polarization signal from inflation. As a postdoctoral researcher at Princeton University from 2010 to 2013, she worked on low-temperature detector characterization, integration, and deployment for ACTPol, the polarization-sensitive receiver on the Atacama Cosmology Telescope. From 2013 to 2016, Newburgh was a Dunlap Fellow at the Dunlap Institute for Astronomy and Astrophysics at the University of Toronto, where she began working on novel calibration methods for CHIME, developing a holographic technique to map the telescope beam. Newburgh joined Yale University as an assistant professor of physics in January 2017. She was subsequently promoted to associate professor.

Research Newburgh's research spans instrumentation, calibration, and data analysis for both 21 cm radio cosmology and CMB experiments. Her work focuses on using these complementary probes to constrain the expansion history of the universe and the properties of fundamental particles.

CHIME Newburgh is a member of the CHIME collaboration, a radio telescope at the Dominion Radio Astrophysical Observatory in British Columbia designed to map the distribution of neutral hydrogen across cosmic time using the 21 cm emission line. Her primary contribution has been developing the holographic beam calibration technique for CHIME, in which a calibration source on a separate steerable dish tracks celestial sources as they transit through CHIME's beam, enabling precise measurement of the telescope's response pattern. This calibration work was critical to estimating the brightness of a fast radio burst detected from a Galactic magnetar in 2020, enabling CHIME to link FRBs to magnetar emission for the first time. CHIME has also become one of the most prolific detectors of fast radio bursts, cataloging 536 FRBs in its first year of operation alone. In 2022, the CHIME collaboration published the first detection of cosmological 21 cm emission, a measurement of the large-scale clustering of hydrogen gas that represents a first step toward using intensity mapping to measure baryon acoustic oscillations and constrain dark energy. In 2019, Newburgh was part of the team that detected repeating fast radio bursts. Her group at Yale has also developed a drone-based beam calibration system, flying radio sources on drones above radio telescopes to produce high-resolution beam maps. This technique, funded by her NSF CAREER Award, has been deployed on CHIME and on prototype arrays for CHIME outriggers.

HIRAX Newburgh is a co-designer of the Hydrogen Intensity Real-time Analysis eXperiment (HIRAX), a planned array of 1024 six-meter radio dishes in South Africa that will map large-scale structure using 21 cm intensity mapping between redshifts 0.8 and 2.5 to constrain dark energy and detect radio transients.

Simons Observatory and CMB-S4 Newburgh works on the Simons Observatory, a ground-based CMB telescope in the Atacama Desert in Chile that achieved first light in 2024. Her group contributes to data acquisition software development for the observatory's Large Aperture Telescope. She is also a member of CMB-S4, the planned next-generation CMB experiment.

Worked examples

Example 1 — a first encounter with Laura Newburgh

Start with the simplest possible case. Write down what Laura Newburgh claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Laura Newburgh before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Laura Newburgh ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Laura Newburgh

In research: Laura Newburgh appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Laura Newburgh in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Laura Newburgh is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century American physicists, 21st-century American women scientists, American cosmologists, so understanding it makes those chapters shorter.
In everyday life: Look for Laura Newburgh outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
