A z 5.7 Ly Emission Line with an Ultra Broad Red Wing

Almost every extreme star forming galaxy has gas outows. Traced by the blue-shifted In z 2 3 LBGs with Ly emission lines, In z 1.8 4.5 gamma-ray burst (GRB) host Astrophysics authors/titles "new"We study the properties of 55 morphologically-identified merging galaxy systems at z~2. These systems are flagged as mergers based on features such as tidal tails, double nuclei, and asymmetry. Our sample is drawn from the MOSFIRE Deep Evolution Field (MOSDEF) survey, along with a control sample of isolated galaxies at the same redshift.

Jul 25, 2018 · The two can be distinguished because the former have smooth spectra and the latter trace the underlying large-scale structure and have spectral structures. The brightness temperature of the synchrotron foreground typically has a spectral dependence of \(\nu^{-2.6}\), or \((1+z)^{2 Dark photon dark matter and fast radio burstsThe nature of dark matter (DM) is still a mystery that may indicate the necessity for extensions of the Standard Model (SM). Light dark photons (DP) may comprise partially or entirely the observed DM density and existing limits for the DP DM parameter space arise from several cosmological and astrophysical sources. In the present work we investigate DP DM using cosmic transients, specifically

Aug 02, 2010 · From the detected emission lines we measure the redshift of the GRB host galaxy to be z= 0.1218 ± 0.0003. 3 HOST GALAXY PROPERTIES 3.1 Host morphology. Visual inspection of the images in R and K bands shows the host to be a nearly face-on galaxy, with clear bulge, disc and spiral arm components. At least two spiral arms can be distinguished, one on either side of the galaxy, DocuSignDocuSign

Gamma-Ray Bursts in the Era of Rapid Followup

We present a status report on the study of gamma-ray bursts (GRBs) in the era of rapid followup using the world's largest robotic optical telescopesthe 2 m Liverpool and Faulkes telescopes. Within the context of key unsolved issues in GRB physics, we describe (1) our innovative software that allows real-time automatic analysis and interpretation of GRB light curves, (2) the novel Gamma-ray burst investigation via polarimetry and Jul 29, 2008 · The primary scientific goal of the GRIPS mission is to revolutionize our understanding of the early universe using -ray bursts. We propose a new generation gamma-ray observatory capable of unprecedented spectroscopy over a wide range of -ray energies (200 keV50 MeV) and of polarimetry (2001000 keV). The -ray sensitivity to nuclear absorption features enables the measurement of

Observation of inverse Compton emission from a long -ray

Nov 20, 2019 · Recently, intense long-lasting emission between 0.2 and 1 teraelectronvolts was observed from GRB 190114C 10, 11. Here we report multi-frequency observations of GRB On the Lyrst Ly narrow band imaging of GRB host galaxies was pre- sented in Fynbo et al. (2002) where we studied the elds of GRB 000301C and GRB 000926, both at redshift z = 2.04.

The GRB itself lasts only a few seconds but is followed by an afterglow that can persist for hours or days. The H.E.S.S. Collaboration observed the afterglow of GRB 190829A, a nearby long GRB. The proximity of this burst allowed it to be detected at

We present the results of deep imaging of the field of GRB 050904 with Suprime-Cam on the Subaru 8.2m telescope. We have obtained a narrow-band (130 A) image centered at 9200 A (NB921) and an i'-band image with total integration times of 56700 and 24060 s, respectively.

One of them is non-stellar Balmer absorption lines. By near-infrared spectroscopy, we discovered three FeLoBALs with Balmer absorption lines among 11 FeLoBALs (three at 1.3 z 1.65 and eight at 2.1 z 2.8). Two z 1 FeLoBALs have been confirmed to have Balmer absorption lines. Balmer absorption lines have similar line widths and velocity shifts to The optical afterglow and host galaxy of GRB 000926 tion system at a redshift of z= 2.0375 ± 0.0007, which in all likelihood is due to gas in the GRB host galaxy (Møller et al. in prep). The OT was observed during the following weeks at the NOT, CA and also with the Isaac Newton Telescope (INT), the 1.0 m telescope at the US Naval Observatory at Flagstaff

Apr 19, 2007 · However, our deep optical imaging and spectroscopy of the location of GRB 060912A using the VLT shows that GRB 060912A more likely originates in a distant star forming galaxy at z=0.937, and is most likely a long burst. This demonstrates the risk in identifying bright, nearby galaxies as the hosts of given GRBs without further supporting evidence. [1905.06337v1] How Do Galaxies trace a large scale May 15, 2019 · Abstract:In the hierarchical theory of galaxy formation, a galaxy overdensity is a hallmark of a massive cosmic structure. However, it is less well understood how different types of galaxies trace the underlying large-scale structure. Motivated by the discovery of a z=3.13 protocluster, we examine how the same structure is populated by Ly$\alpha$-emitting galaxies (LAEs).
