GALAXY MERGERS AS A SOURCE OF COSMIC RAYS, NEUTRINOS, AND GAMMA RAYS [PDF]
, 2014 We investigate the shock acceleration of particles in massive galaxy mergers or collisions, and show that cosmic rays (CRs) can be accelerated up to the second knee energy ∼0.1–1 EeV and possibly beyond, with a hard spectral index of Γ ≈ 2. Such CRs lose

Observing Galaxy Mergers at the Epoch of Reionization [PDF]
The Astrophysical Journal, 2018 Abstract The galaxies with photometric redshifts observed in a close angular proximity might be either projection coincidences, strongly lensed images of the same galaxy, or separate galaxies that are in a stage of merging. We search for the groups of galaxies in the Hubble Ultra Deep Field (HUDF09) in z ∼ 7 and z ∼ 8 drop-out samples ...

Advanced Electronic Materials, EarlyView.A blackbody‐sensitive infrared photodetector comprised of an open‐shell conjugated polymer demonstrates high sensitivity without cooling and exceptional radiation hardness, surpassing inorganic compound semiconductor devices. This functionality, inherent to the polymer semiconductor, provides a new frontier for low‐cost, size, weight, and power space ...

Merger-Induced Metallicity Dilution in Cosmological Galaxy Formation Simulations
, 2018 Observational studies have revealed that galaxy pairs tend to have lower gas-phase metallicity than isolated galaxies. This metallicity deficiency can be caused by inflows of low-metallicity gas due to the tidal forces and gravitational torques ...

Compliant Robotics in Space: A Prospective Review of Soft and Deformable Systems for Space Missions
Advanced Intelligent Systems, EarlyView.Compliant robots are increasingly becoming integral to space exploration due to their adaptability, flexibility, and lightweight design. This article reviews categories such as soft, reconfigurable, and hyper‐redundant robots and their evolving role in enhancing space missions.

Stellar populations in gas-rich galaxy mergers I. Dependence on star formation history
, 1998 We investigate the nature of stellar populations of major galaxy mergers between late-type spirals considerably abundant in interstellar medium by performing numerical simulations designed to solve both the dynamical and chemical evolution in a self ...

FAST MOLECULAR OUTFLOWS IN LUMINOUS GALAXY MERGERS: EVIDENCE FOR QUASAR FEEDBACK FROM HERSCHEL [PDF]
, 2013 We report the results from a systematic search for molecular (OH 119 μm) outflows with Herschel/PACS in a sample of 43 nearby (z < 0.3) galaxy mergers, mostly ultraluminous infrared galaxies (ULIRGs) and QSOs. We find that the character of the OH feature

Galaxy mergers and gravitational lens statistics [PDF]
The Astrophysical Journal, 1994 We investigate the impact of hierarchical galaxy merging on the statistics of gravitational lensing of distant sources. Since no definite theoretical predictions for the merging history of luminous galaxies exist, we adopt a parametrized prescription, which allows us to adjust the expected number of pieces comprising a typical present galaxy at z=0.65.

Artificial Intelligences: A Bridge Toward Diverse Intelligence and Humanity's Future
Advanced Intelligent Systems, EarlyView.Many discussions of artificial intelligence fail to address deeper questions being raised by advances in developmental biology, neuroscience, bioengineering, and philosophy of mind. Novel beings, including technologically and biologically augmented humans, engineered life forms, hybrots, and others, require tools of the emerging field of diverse ...
