Possibility of Multi-tev Secondary Gamma Rays From Grb221009a

The brightest gamma ray burst (GRB) ever observed, GRB221009A, produced a surprisingly large flux of gamma rays with multi-TeV energies, which are expected to be absorbed in interactions with extragalactic background light (EBL). If the highest energy gamm ...

Virgo Filaments: III. The gas content of galaxies in filaments as predicted by the GAEA semi-analytic model

Pascale Jablonka

Galaxy evolution depends on the environment in which galaxies are located. The various physical processes (ram-pressure stripping, tidal interactions, etc.) that are able to affect the gas content in galaxies have different efficiencies in different enviro ...

Towards quantum telescopes (Abstract: Y07.00001 )

Edoardo Charbon, Claudio Bruschini, Samuel Burri, Ermanno Bernasconi

The idea of exploiting quantum features of light to perform more precise astrophysical measurements is a long-desired goal of both the optics and astrophysics communities, but only recently have theoretical proposals started to be experimentally implemente ...

An environment-dependent halo mass function as a driver for the early quenching of z ≥ 1.5 cluster galaxies

Yannick Michael Bahé

Many z approximate to 1.5 galaxies with a stellar mass (M star) >= 1010M(circle dot) are already quenched in both galaxy clusters (>50 per cent) and the field (>20 per cent), with clusters having a higher quenched fraction at all stellar masses compared to ...

CEERS Key Paper. VI. JWST/MIRI Uncovers a Large Population of Obscured AGN at High Redshifts

Michaela Hirschmann

Mid-infrared (mid-IR) observations are powerful in identifying heavily obscured active galactic nuclei (AGN) that have weak emission in other wavelengths. Data from the Mid-Infrared Instrument (MIRI) on board the James Webb Space Telescope provides an exce ...

The Robotic Multiobject Focal Plane System of the Dark Energy Spectroscopic Instrument (DESI)

Jean-Paul Richard Kneib, Mohamed Bouri, Luzius Gregor Kronig, Philipp Hörler

A system of 5020 robotic fiber positioners was installed in 2019 on the Mayall Telescope, at Kitt Peak National Observatory. The robots automatically retarget their optical fibers every 10-20 minutes, each to a precision of several microns, with a reconfig ...

ShapePipe: A new shape measurement pipeline and weak-lensing application to UNIONS/CFIS data

Austin Chandler Peel

Context. The Ultraviolet Near-Infrared Optical Northern Survey (UNIONS) is an ongoing collaboration that will provide the largest deep photometric survey of the northern sky in four optical bands to date. As part of this collaboration, the Canada-France Im ...

Crossed Molecular Beams and Theoretical Studies of the O(P-3)+1,2-Butadiene Reaction: Dominant Formation of Propene plus CO and Ethylidene plus Ketene Molecular Channels

Adriana Caracciolo, Silvia Tanteri

Detailed understanding of the mechanism of the combustion relevant multichannel reactions of O(P-3) with unsaturated hydrocarbons (UHs) requires the identification of all primary reaction products, the determination of their branching ratios and assessment ...

H0LiCOW-V. New COSMOGRAIL time delays of HE 0435-1223: H-0 to 3.8 per cent precision from strong lensing in a flat Lambda CDM model

Frédéric Courbin, Georges Meylan, Vivien François Bonvin, Malte Tewes

We present a new measurement of the Hubble Constant H-0 and other cosmological parameters based on the joint analysis of three multiply imaged quasar systems with measured gravitational time delays. First, we measure the time delay of HE 0435-1223 from 13- ...

Deep Cfht Y-Band Imaging Of Vvds-F22 Field. I. Data Products And Photometric Redshifts

Huanyuan Shan

We present our deep Y-band imaging data of a two square degree field within the F22 region of the VIMOS VLT Deep Survey. The observations were conducted using the WIRCam instrument mounted at the Canada-France-Hawaii Telescope (CFHT). The total on-sky time ...

SDSS-IV eBOSS emission-line galaxy pilot survey

Zhirui Xu, Yi Zhang, Jean-Paul Richard Kneib, Eduardo Sanchez, Anand Stéphane Raichoor, David Schlegel, Timothée Guy Olivier Delubac

The Sloan Digital Sky Survey IV extended Baryonic Oscillation Spectroscopic Survey (SDSS-IV/eBOSS) will observe 195 000 emission-line galaxies (ELGs) to measure the baryonic acoustic oscillation (BAO) standard ruler at redshift 0.9. To test different ELG s ...

Measuring subhalo mass in redMaPPer clusters with CFHT Stripe 82 Survey

Jean-Paul Richard Kneib, Huanyuan Shan

We use the shear catalogue from the CFHT Stripe-82 Survey to measure the subhalo masses of satellite galaxies in redMaPPer clusters. Assuming a Chabrier initial mass function and a truncated NFW model for the subhalo mass distribution, we find that the sub ...

Search for Solar Axions by the CERN Axion Solar Telescope with He-3 Buffer Gas: Closing the Hot Dark Matter Gap

Manuel Gómez Marzoa

The CERN Axion Solar Telescope has finished its search for solar axions with He-3 buffer gas, covering the search range 0.64 eV less than or similar to ma less than or similar to 1.17 eV. This closes the gap to the cosmological hot dark matter limit and ac ...
