Hadronic nature of high-energy emission from the Galactic ridge

We show that the IceCube observation of the Galactic neutrino-flux component confirms the hint of detection of neutrinos from the Galactic ridge (the inner part of the Milky Way disk within the Galactic longitude IlI < 30(degrees)), previously reported by ...

Exploring and mapping the diffuse interstellar band at 862nm

Shuangqing Liao

Context. Di ffuse interstellar bands (DIBs) are common interstellar absorption features in spectroscopic observations but their origins remain unclear. DIBs play an important role in the life cycle of the interstellar medium (ISM) and can also be used to t ...

Signatures of anisotropic diffusion around PeVatrons in 100 TeV gamma-ray data

The Tibet AS gamma collaboration has reported a diffuse gamma-ray emission signal from the Galactic Plane. We consider the possibility that the diffuse emission from the outer Galactic Plane at the highest energies is produced by cosmic rays spreading from ...

A Long Time Ago in a Galaxy Far, Far Away: A Candidate z similar to 12 Galaxy in Early JWST CEERS Imaging

Michaela Hirschmann

We report the discovery of a candidate galaxy with a photo -z of z similar to 12 in the first epoch of the James Webb Space Telescope (JWST) Cosmic Evolution Early Release Science Survey. Following conservative selection criteria, we identify a source with ...

Analysis of Red Supergiants in VDBH 222

Carmela Lardo

Recent surveys uncovered new young massive clusters (YMCs) that host dozens of red supergiants (RSGs) in the inner Milky Way. These clusters are ideal for studying the most recent and violent star formation events in the inner Galaxy. However, due to the h ...

Overview of the DESI Legacy Imaging Surveys

Jean-Paul Richard Kneib, Johan Comparat, Anand Stéphane Raichoor, Huanyuan Shan, David Schlegel, Timothée Guy Olivier Delubac, Claudio Gorgoni, Elodie Marie Charlène Savary, Tobias Gabriel Meier, Alejandro Alvarez, Arjun Dey, Paul Carter, Abhijit Saha

The DESI Legacy Imaging Surveys (http://legacysurvey.org/) are a combination of three public projects (the Dark Energy Camera Legacy Survey, the Beijing-Arizona Sky Survey, and the Mayall z-band Legacy Survey) that will jointly image approximate to 14,000 ...

Observations of Sagittarius A* during the pericenter passage of the G2 object with MAGIC

Thomas Günther Bretz

Context. We present the results of a multi-year monitoring campaign of the Galactic center (GC) with the MAGIC telescopes. These observations were primarily motivated by reports that a putative gas cloud (G2) would be passing in close proximity to the supe ...

The Gaia-ESO Survey: Galactic evolution of sulphur and zinc

Carmela Lardo

Context. Due to their volatile nature, when sulphur and zinc are observed in external galaxies, their determined abundances represent the gas-phase abundances in the interstellar medium. This implies that they can be used as tracers of the chemical enrichm ...

Planck intermediate results XXX. The angular power spectrum of polarized dust emission at intermediate and high Galactic latitudes

Julien Lesgourgues, Fabio Finelli

The polarized thermal emission from diffuse Galactic dust is the main foreground present in measurements of the polarization of the cosmic microwave background (CMB) at frequencies above 100 GHz. In this paper we exploit the uniqueness of the Planck HFI po ...

Stellar kinematics using a third integral of motion: method and application on the Andromeda galaxy

Olga Tihhonova

We probe the feasibility of describing the structure of a multicomponent axisymmetric galaxy with a dynamical model based on the Jeans equations while taking into account a third integral of motion. We demonstrate that using the third integral in the form ...
