We report the detection of a rich spectrum of more than one hundred optical emission lines from neutral/molecular gas in the photodissociation region (PDR) around the mini-starburst cluster NGC 346 in the Small Magellanic Cloud.
Astrophysics of Galaxies
We perform a detailed study of the cosmological bias of gravitational gave (GW) events produced by binary black hole mergers (BBHM).

For the lowest SNR spectra ($\rm{SNR=3}$), the CNN reliably recovers and localizes EW$_{\rm{MgII, 2796}}^{\rm{rest}}$ $\geq$ 0. 75 \AA\, absorbers.

We present icarogw 2. 0, a pure CPU/GPU python code developed to infer astrophysical and cosmological population properties of noisy, heterogeneous, and incomplete observations.

Once the PSF is estimated, it can be removed from the data through the so-called deconvolution process, leading to images of improved spatial resolution.
Instrumentation and Methods for Astrophysics Computational Physics
The Hitomi X-ray satellite mission carried unique high-resolution spectrometers that were set to revolutionize the search for sterile neutrino dark matter (DM) by looking for narrow X-ray lines arising from DM decays.

We describe the eccentricity distribution for apparently single-transiting planetary systems with a Rayleigh distribution with sigma = 0. 19 (+0. 04, -0. 03), and for multi-transit systems with sigma = 0. 03 (+0. 02, -0. 01).

However, it has been difficult to take full advantage of all these RMs as the individual catalogs have been published in many different places, and in many different formats.

In this work, we apply self-supervised learning with instance differentiation to learn a robust, multi-purpose representation for use in radio astronomy.

However its verification with high accuracy is challenging due to various foregrounds and selection effects, and possible violation of the cosmological principle has been reported in the literature.
