Inconsistencies and Lurking Pitfalls in the Magnitude–Frequency Distribution of High-Resolution Earthquake Catalogs

Seismological Research Letters, 2020
Earthquake catalogs describe the distribution of earthquakes in space, time, and magnitude, which is essential information for earthquake forecasting and the assessment of seismic hazard and risk.

HEROES: The Hawaii eROSITA Ecliptic Pole Survey Catalog [PDF]

, 2023
We present a seven band (g, r, i, z, y, NB816, NB921) catalog derived from a Subaru Hyper Suprime-Cam (HSC) imaging survey of the North Ecliptic Pole (NEP). The survey, known as HEROES, consists of 44 sq. deg of contiguous imaging reaching median 5-sigma depths of g: 26.5, r: 26.2, i: 25.7, z: 25.1, y: 23.9, NB816: 24.4, NB921: 24.4 mag.

Mining gravitational-wave catalogs to understand binary stellar evolution: A new hierarchical Bayesian framework [PDF]

Physical Review D, 2018
Catalogs of stellar-mass compact binary systems detected by ground-based gravitational-wave instruments (such as LIGO and Virgo) will offer insights into the demographics of progenitor systems and the physics guiding stellar evolution.

CANDELS Multi-wavelength Catalogs: Source Identification and Photometry in the CANDELS Extended Groth Strip [PDF]

, 2017
We present a 0.4–8 μm multi-wavelength photometric catalog in the Extended Groth Strip (EGS) field. This catalog is built on the Hubble Space Telescope (HST) WFC3 and ACS data from the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey ...

Spitzer Matching Survey of the UltraVISTA Ultra-deep Stripes (SMUVS): Full-mission IRAC Mosaics and Catalogs [PDF]

Astrophysical Journal Supplement Series, 2018
This paper describes new deep 3.6 and 4.5 μm imaging of three UltraVISTA near-infrared survey stripes within the COSMOS field. The observations were carried out with Spitzer’s Infrared Array Camera (IRAC) for the Spitzer Matching Survey of the UltraVISTA

Determination of homogenized effective temperatures from stellar catalogs [PDF]

Baltic Astronomy, 20, 91-106, 2011, 2011
Some selected catalogs of the effective temperatures for F, G and K stars are analyzed. By an improved technique we estimate the external errors of these catalogs from data intercomparisons. The values of the effective temperatures are then averaged with the appropriate weights to produce a mean homogeneous catalog based on the selected data.

Building IoT-Based Applications for Smart Cities: How Can Ontology Catalogs Help?

IEEE Internet of Things Journal, 2018
The Internet of Things (IoT) plays an ever-increasing role in enabling smart city applications. An ontology-based semantic approach can help improve interoperability between a variety of IoT-generated as well as complementary data needed to drive these ...
