Cosmic rays are deemed to be generated by a process known as “Fermi acceleration” in which charged particles scatter against magnetic fluctuations in astrophysical plasma [...]

Perhaps the most basic question we can ask about cosmological correlations is how their strength changes as we smoothly vary kinematic parameters. The answer is encode [...]

Recent results from type Ia supernovae (SNe Ia) and baryon acoustic oscillations (BAO), in combination with cosmic microwave background (CMB) measurements, have focused r [...]

Diffusion damping of the cosmic microwave background (CMB) power spectrum results from imperfect photon-baryon coupling in the pre-recombination plasma. Energy release at [...]

While thousands of exoplanets have been discovered to date, there are still many open questions with regards to their formation, evolution, and occurrence. These questio [...]

Just like the moon causes tides on the Earth, the Milky Way causes tides on star systems dropped into our galaxy. Globular clusters and dwarf galaxies that fall into the [...]

The J-region Asymptotic Giant Branch (JAGB) method is a standard candle based on the intrinsic luminosities of carbon stars in the near infrared. We directly constrain t [...]

We present estimates of the ultraviolet (UV) and hydrogen ionizing photon density contributed by galaxies of luminosities from 𝑀uv ≈ −25 to 𝑀uv = −5 at redshifts 5 ≤ 𝑧 ≤ [...]

The MUonE experiment aims to extract the hadronic contribution to the muon anomalous magnetic moment from a precise measurement of the muon-electron differential scatteri [...]

As a part of the Field Course in Astrophysics, I was privileged to visit Chile for an observing run at the Magellan Telescopes atop the Andean foothills of the Atacama de[...]

Dark matter particles with a mass around 1 eV can decay into near-infrared photons. Utilizing available public blank sky observations from the NIRSpec IFU on the James We [...]

We introduce DeepBench, a Python library that employs mechanistic models (i.e., analytic mathematical models) to simulate data that represent physics-related objects and [...]

Novel carbon dioxide removal (CDR) technologies are increasingly being considered as potentially useful tools to combat climate change. For specific atmospheric carbon di [...]

Wave or fuzzy dark matter that is produced with relativistic wave numbers exhibits free-streaming effects analogous to warm or hot particle dark matter with relativistic [...]

Collisionless shock waves, found in supernova remnants, interstellar, stellar, and planetary environments, and laboratories, are one of nature’s most powerful particle ac [...]

Low-mass (sub-eV) scalar field dark matter may induce apparent oscillations of fundamental constants, resulting in corresponding oscillations of the size and the index of [...]

The long-standing $4.2⁢σ$ muon $g−2$ anomaly may be the result of a new particle species which could also couple to dark matter and mediate its annihilations in the early [...]

We report a laser-plasma experiment that was carried out at the LMJ-PETAL facility and realized the first magnetized, turbulent, supersonic (Ma_turb ≈2.5) plasm [...]

Millicharged dark matter particles can be efficiently captured by the Sun, where they annihilate into tau leptons, leading to the production of high-energy neutrinos. In [...]

I present a collection of forecasting, analysis, and instrumentation work related to the science cases and detector development for an upcoming camera for the 10-meter So [...]

In models featuring extra spatial dimensions, particle collisions in the early Universe can produce Kaluza-Klein gravitons. Such particles will later decay, potentially i [...]

The near-infrared transmission spectrum of the warm sub-Neptune exoplanet GJ 1214 b has been observed to be flat and featureless, implying a high metallicity atmosphere w [...]

Models developed for Earth are often applied in exoplanet contexts. Validation in extraterrestrial settings can provide an important test of model realism and increase ou [...]

We explore the physics of relativistic gapless phases defined by a mixed anomaly between two generalized conserved currents. The gapless modes can be understood as Goldst [...]

Accelerator-based experiments reliant on charged pion and kaon decays to produce muon-neutrino beams also deliver an associated powerful flux of muons. Therefore, these e [...]
