Kavli Affiliate: Luis C. Ho | First 5 Authors: Weimin Yi, W. N. Brandt, Q. Ni, Luis C. Ho, Bin Luo | Summary: We present the first near-IR spectroscopy and joint analyses of multi-wavelength observations for SDSS J082747.14+425241.1, a dust-reddened, weak broad emission-line quasar (WLQ) undergoing a remarkable broad absorption line (BAL) transformation. The systemic […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Yi Zhou, Masahiro Kaneko, Danushka Bollegala, , | Summary: Sense embedding learning methods learn different embeddings for the different senses of an ambiguous word. One sense of an ambiguous word might be socially biased while its other senses remain unbiased. In comparison to the numerous prior work […]
Kavli Affiliate: Risa Wechsler | First 5 Authors: Monica Valluri, Solene Chabanier, Vid Irsic, Eric Armengaud, Michael Walther | Summary: Despite efforts over several decades, direct-detection experiments have not yet led to the discovery of the dark matter (DM) particle. This has led to increasing interest in alternatives to the Lambda CDM (LCDM) paradigm and […]

Kavli Affiliate: Claudio Ricci | First 5 Authors: Rogério Riffel, Luis G. Dahmer-Hahn, Rogemar A. Riffel, Thaisa Storchi-Bergmann, Natacha Z. Dametto | Summary: We use Gemini Near-Infrared Integral Field Spectrograph (NIFS) adaptive optics assisted data-cubes to map the stellar population of the inner few hundred parsecs of a sample of 18 nearby Seyfert galaxies. The […]
Kavli Affiliate: Nicola Omodei | First 5 Authors: Kristi Engel, Jordan Goodman, Petra Huentemeyer, Carolyn Kierans, Tiffany R. Lewis | Summary: Gamma-rays, the most energetic photons, carry information from the far reaches of extragalactic space with minimal interaction or loss of information. They bring messages about particle acceleration in environments so extreme they cannot be […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Keith Bechtol, Simon Birrer, Francis-Yan Cyr-Racine, Katelin Schutz, Susmita Adhikari | Summary: The non-linear process of cosmic structure formation produces gravitationally bound overdensities of dark matter known as halos. The abundances, density profiles, ellipticities, and spins of these halos can be tied to the underlying fundamental […]
Kavli Affiliate: Salman Habib, Katrin Heitmann | First 5 Authors: Marcelo A. Alvarez, Arka Banerjee, Simon Birrer, Salman Habib, Katrin Heitmann | Summary: Powerful new observational facilities will come online over the next decade, enabling a number of discovery opportunities in the “Cosmic Frontier”, which targets understanding of the physics of the early universe, dark […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Rong-Yang Sun, Hui-Ke Jin, Hong-Hao Tu, Yi Zhou, | Summary: The nature of the ground state for the $S = 1/2$ kagome Heisenberg antiferromagnet (KHAF) has been elusive. We revisit this challenging problem and provide numerical evidence that its ground state might be a chiral spin liquid. […]
Kavli Affiliate: Avi Shporer | First 5 Authors: Prajwal Niraula, Avi Shporer, Ian Wong, Julien de Wit, | Summary: Space-based photometric missions widely use statistical validation tools for vetting transiting planetary candidates, particularly when other traditional methods of planet confirmation are unviable. In this paper, we refute the planetary nature of three previously validated planets […]
