Germanium‐Based Mid‐Infrared Integrated Photonics

Laser &Photonics Reviews, EarlyView.
The mid‐infrared (mid‐IR) spectral range is a part of the electromagnetic spectrum in which most of the molecules have vibrational and rotational resonances. Photonics integration in this wavelength range have thus seen a burst of interest in the recent years, mainly driven by applications related with the detection of chemical and biological ...

The MaNGA Dwarf Galaxy Sample (MaNDala): Stellar Profiles and Gradients Characterization

The Astronomical Journal
We derived robust radial profiles and inner/outer gradients of various stellar population (SP) properties for a sample of 124 bright dwarf galaxies, 10 ^7.53 ≤ M _* / M _⊙ ≤ 10 ^9.06 , from the MaNDala sample, using integral field spectroscopy ...

Compact radio sources and jet-driven AGN feedback in the early Universe: Constraints from integral-field spectroscopy [PDF]

, 2007
To investigate the impact of radio jets during the formation epoch of their massive host galaxies, we present an analysis of two massive, log(M_stel/ M_sun)~10.6 and 11.3, compact radio galaxies at z=3.5, TNJ0205+2242 and TNJ0121+1320.

Galaxy Spectroscopy without Spectra: Galaxy Properties from Photometric Images with Conditional Diffusion Models

The Astrophysical Journal
Modern spectroscopic surveys can only target a small fraction of the vast amount of photometrically cataloged sources in wide-field surveys. Here, we report the development of a generative artificial intelligence (AI) method capable of predicting optical

Infrared Spectroscopy of Blue Dwarf Galaxies

The Astrophysical Journal, 1997
We present a survey of the near-infrared emission lines of eight blue dwarf galaxies. These galaxies have advantages for study of the excitation of the interstellar medium by starbursts because the effects are relatively undiluted by the quiescent stellar population, the star formation episodes usually appear to be of short duration, and the effects of

Mind and Cosmos as Throughput Systems: A Convergence Through the Throughput Model

Systems Research and Behavioral Science, EarlyView.
ABSTRACT This paper advances a conceptual and mathematical foundations approach by applying the throughput model (TPM) to cosmic phenomena, reframing the universe as an extended information processing system. TPM's four stages, Perception, Information, Judgement and Decision Choice, are reformulated in explicit information‐theoretic and dynamical ...

The MOSDEF-KCWI Survey: Spectral Properties of Lyα Halos around z ∼ 2 Star-forming Galaxies

The Astrophysical Journal
We present Keck Cosmic Web Imager integral field observations of extended Ly α emission in the circumgalactic medium of 27 typical star-forming galaxies at z ∼ 2, drawn from the Multi-Object Spectrometer for Infra-Red Exploration (MOSFIRE) Deep Evolution

Galaxies Probing Galaxies in PRIMUS - I. Sample, Spectroscopy, and Characteristics of the z~0.5 MgII-Absorbing Circumgalactic Medium

, 2017
Spectroscopy of background QSO sightlines passing close to foreground galaxies is a potent technique for studying the circumgalactic medium (CGM).

Winter‐active spiders (Clubiona) have a hyperactive antifreeze protein with a unique beta‐solenoid fold

The FEBS Journal, EarlyView.
Antifreeze proteins from winter‐active spiders were purified using their affinity for ice. After LC–MSMS characterization, corresponding transcripts were identified. The antifreeze protein folds as a β‐solenoid with a large flat ice‐binding site on one surface and can bind to ice crystals and prevent their growth at −4 °C.
