Od prvih galaksij do temne snovi: Življenjepis našega vesolja
Maja Ratej , Maruša Bradač
Video in druga učna gradiva
Oznake: astronomy
Ljudje smo se od nekdaj spraševali, od kod smo in kam gremo. V tem pogovoru bomo razkrili, kako astronomi vidimo začetke nastanka galaksij in kako preučujemo lastnosti temne snovi, ki močno vpliva na razvoj našega Vesolja.

Spatially resolved emission lines in galaxies at 4 ≤ z < 10 from the JADES survey
Roberta Tripodi, Maruša Bradač
Izvirni znanstveni članek
Oznake: star formation;imaging spectroscopy;high red-shift galaxies;
We present the first statistical investigation of spatially resolved emission-line properties in a sample of 63 low-mass galaxies at 4 ≤ z < 10 using James Webb Space Telescope (JWST)/NIRSpec Micro Shutter Assembly (MSA) data from the JWST Advanced Deep Extragalactic (JADES) survey, focusing on deep ...

ǂThe ǂrate and contribution of mergers to mass assembly from NIRCam observations of galaxy candidates up to 13.3 billion years ago
Nicoló Dalmasso, Antonello Calabrò, Nicha Leethochawalit, Maruša Bradač
Izvirni znanstveni članek
Oznake: galaxies formation;star formation;high-redshift galaxies;
We present an analysis of the galaxy merger rate in the redshift range 4.0 < z < 9.0 (i.e. about 1.5 to 0.5 Gyr after the big bang) based on visually identified galaxy mergers from morphological parameter analysis. Our data set is based on high-resolution NIRCam JWST data (a combination of F150W and ...

BEACON: JWST NIRCam Pure-parallel imaging survey
Takahiro Morishita, Charlotte Mason, Kimi C. Kreilgaard, Maruša Bradač
Izvirni znanstveni članek
Oznake: galaxies;high-redshift galaxies;reionization;
We introduce the Bias-free Extragalactic Analysis for Cosmic Origins with NIRCam (BEACON) survey, a JWST Cycle 2 program allocated up to 600 pure-parallel hours of observations. BEACON explores high-latitude areas of the sky with JWST/NIRCam over ∼100 independent sight lines, totaling ∼0.3 deg2, rea ...

ǂThe ǂJWST/PASSAGE Survey

Izvirni znanstveni članek
Oznake: Lyman-alpha galaxies;high-redshift galaxies;reionization;
Lyα emission is one of a few observable features of galaxies that can trace the neutral hydrogen content in the Universe during the Epoch of Reionization (EoR). To accomplish this, we need an efficient way to survey for Lyα emitters (LAEs) at redshifts beyond 7, requiring unbiased emission-line obse ...

Anatomy of a z = 6 Lyman-α emitter down to parsec scales
Matteo Messa, Eros Vanzella, Federica Loiacono, Pietro Bergamini, Marco Castellano, Maruša Bradač
Izvirni znanstveni članek
Oznake: gravitational lensing;HII regions;high-redshift galaxies;star formation;
We present a detailed JWST/NIRSpec and NIRCam analysis of a gravitationally lensed galaxy (μ = 17 ‑ 21) at a redshift of 6.14 magnified by the Hubble Frontier Field galaxy cluster MACS J0416. The target galaxy is a typical compact and UV-faint (MUV = ‑17.8) Lyman-α emitter, yet the large magnificati ...
