High-resolution G-band images of the interior of a supergranulation cell show ubiquitous bright points (BPs; some 0.3 BPs per Mm2). They are located in...
Brightness Fluctuation Spectra of Sun-like Stars. I. The Mid-frequency Continuum
We analyze space-based time-series photometry of Sun-like stars, mostly in the Pleiades, but also field stars and the Sun itself. We focus on timescales between...
Broadband Multi-wavelength Properties of M87 during the 2017 Event Horizon Telescope Campaign
In 2017, the Event Horizon Telescope (EHT) Collaboration succeeded in capturing the first direct image of the center of the M87 galaxy. The asymmetric ring...
We present Spitzer/IRAC and MIPS 24 μm observations for 28 brown dwarfs in the Upper Scorpius (UppSco) region. We find a disk fraction of 10.7%+8.7% -3.3%. One...
BVRI Photometry of QSO 0957+561A, B: Observations, New Reduction Method, and Time Delay
CCD observations of the gravitational lens system Q0957+561A, B in the BVRI bands are presented in this paper. The observations, taken with the 82 cm IAC-80...
Can Cuspy Dark-matter-dominated Halos Hold Cored Stellar Mass Distributions?
According to the current concordance cosmological model, dark matter (DM) particles are collisionless and produce self-gravitating structures with a central...
Candidate Gravitationally Lensed Dusty Star-forming Galaxies in the Herschel Wide Area Surveys
We present a list of candidate gravitationally lensed dusty star-forming galaxies (DSFGs) from the HerMES Large Mode Survey and the Herschel Stripe 82 Survey...
Capturing the Physics of MaNGA Galaxies with Self-supervised Machine Learning
As available data sets grow in size and complexity, advanced visualization tools enabling their exploration and analysis become more important. In modern...
Carbon Abundances in Compact Galactic Planetary Nebulae: An Ultraviolet Spectroscopic Study with the Space Telescope Imaging Spectrograph (STIS)
We surveyed a sample of compact Galactic planetary nebulae (PNe) with the Space Telescope Imaging Spectrograph on the Hubble Space Telescope (HST) to determine...
