Short-period Heartbeat Binaries from TESS Full-Frame Images
Siddhant Solanki, Agnieszka M. Cieplak, Jeremy Schnittman +9
We identify short-period ( days) binary systems in the TESS data, of which are heartbeat binaries (HB). The sample is mostly a mix of A and B-type stars…
Short-Period Variables in TESS Full-Frame Image Light Curves Identified via Convolutional Neural Networks
Greg Olmschenk, Richard K. Barry, Stela Ishitani Silva +9
The Transiting Exoplanet Survey Satellite (TESS) mission measured light from stars in ~85% of the sky throughout its two-year primary mission, resulting in millions of TESS 30-minu…
Electromagnetic probes of primordial black holes as dark matter
Y. Ali-Haimoud, S. Clesse, J. Garcia-Bellido +91
The LIGO discoveries have rekindled suggestions that primordial black holes (BHs) may constitute part to all of the dark matter (DM) in the Universe. Such suggestions came from 1)…
Response approach to the squeezed-limit bispectrum: application to the correlation of quasar and Lyman- forest power spectrum
Chi-Ting Chiang, Agnieszka M. Cieplak, Fabian Schmidt +1
The squeezed-limit bispectrum, which is generated by nonlinear gravitational evolution as well as inflationary physics, measures the correlation of three wavenumbers, in the config…
Characterizing the Lyman- flux probability distribution function using Legendre polynomials
Agnieszka M. Cieplak, Anže Slosar
The Lyman- forest is a highly non-linear field with a lot of information available in the data beyond the power spectrum. The flux probability distribution function (PDF) has be…
Towards physics responsible for large-scale Lyman- forest bias parameters
Agnieszka M. Cieplak, Anže Slosar
Using a series of carefully constructed numerical experiments based on hydrodynamic cosmological SPH simulations, we attempt to build an intuition for the relevant physics behind t…
Experimental Limits on Primordial Black Hole Dark Matter from the First Two Years of Kepler Data
Kim Griest, Agnieszka M. Cieplak, Matthew J. Lehner
We present the analysis on our new limits of the dark matter (DM) halo consisting of primordial black holes (PBHs) or massive compact halo objects (MACHOs). We present a search of…
Improved Theoretical Predictions of Microlensing Rates for the Detection of Primordial Black Hole Dark Matter
Agnieszka M. Cieplak, Kim Griest
Primordial Black Holes (PBHs) remain a Dark Matter (DM) candidate of the Standard Model of Particle Physics. Previously, we proposed a new method of constraining the remaining PBH…
Microlensing of Kepler Stars as a Method of Detecting Primordial Black Hole Dark Matter
Kim Griest, Matthew J. Lehner, Agnieszka M. Cieplak +1
If the Dark Matter consists of primordial black holes (PBHs), we show that gravitational lensing of stars being monitored by NASA's Kepler search for extra-solar planets can cause…
