Virgo Filaments. IV. Using WISE to Measure the Modification of Star-forming Disks in the Extended Regions Around the Virgo Cluster

open access: yesThe Astrophysical Journal
Recent theoretical work and targeted observational studies suggest that filaments are sites of galaxy preprocessing. The aim of the WISESize project is to directly probe galaxies over the full range of environments to quantify and characterize extrinsic ...

Effects of Forbush Decreases on the Global Electric Circuit

open access: yesSpace Weather, Volume 22, Issue 4, April 2024.
Abstract The suppression of high‐energy cosmic rays, known as Forbush decreases (FDs), represents a promising factor in influencing the global electric circuit (GEC) system. Researchers have delved into these effects by examining variations, often disruptive, of the potential gradient (PG) in ground‐based measurements taken in fair weather regions.

JWST Discovery of a Very Fast Biconical Outflow of Warm Molecular Gas in the Nearby Ultraluminous Infrared Galaxy F08572+3915 NW

open access: yesThe Astrophysical Journal
We present new James Webb Space Telescope (JWST) Mid-Infrared Instrument Medium-Resolution Spectrometer observations of the nearby ultraluminous infrared galaxy (ULIRG) F08572+3915 NW. These integral field spectroscopic (IFS) data reveal a kpc-scale warm-

X-Raying CAMELS: Constraining Baryonic Feedback in the Circumgalactic Medium with the CAMELS Simulations and eRASS X-Ray Observations

open access: yesThe Astrophysical Journal
The circumgalactic medium (CGM) around massive galaxies plays a crucial role in regulating star formation and feedback. Using the Cosmology and Astrophysics with MachinE Learning Simulations (CAMELS) suite, we develop emulators for the X-ray surface ...

The Era of Kilometer-Scale Neutrino Detectors

open access: yesAdvances in High Energy Physics, 2013
Neutrino astronomy beyond the Sun was first imagined in the late 1950s; by the 1970s, it was realized that kilometer-scale neutrino detectors were required.

Measuring the Intracluster Light Fraction with Machine Learning

open access: yesThe Astrophysical Journal
The intracluster light (ICL) is an important tracer of a galaxy cluster’s history and past interactions. However, only small samples have been studied to date due to its very low surface brightness and the heavy manual involvement required for the ...

Strong LensIng and Cluster Evolution (SLICE) with JWST: Early Results, Lens Models, and High-redshift Detections

open access: yesThe Astrophysical Journal
We leverage JWST’s superb resolution to derive strong-lensing mass maps of 14 clusters, spanning a redshift range of z  ∼ 0.25–1.06 and a mass range of M _500  ∼ 2–12 × 10 ^14 M _⊙ , from the Strong LensIng and Cluster Evolution (SLICE) JWST program ...

A Pilot Study for the CSST Slitless Spectroscopic Quasar Survey Based on Mock Data

open access: yesThe Astrophysical Journal
The wide survey of the Chinese Space Station Telescope (CSST) will observe a large field of 17,500 deg ^2 . The GU, GV, and GI grism observations of CSST will cover the wavelength range from 2550 to 10000 Å at a resolution of R  ∼ 200 and a depth of ...

Cross Calibration of Galaxy Cluster Temperatures Measured with NuSTAR, XMM-Newton, and Chandra

open access: yesThe Astrophysical Journal
The use of galaxy clusters to constrain cosmology is limited in part due to uncertainties in derived cluster masses, which often depend on the gas temperature. Unfortunately, there exists a longstanding discrepancy in temperature measurements of the same

Pacific Ocean Neutrino Experiment

open access: yesUniverse
Following the breakthrough discoveries of very-high-energy neutrinos of astrophysical origin by IceCube, a new field of research, neutrino astronomy, was established in the previous decade.
