Hidden in Pixels. I. Discovery of dual "little red dots" indicates excess clustering on kilo-parsec scales
Takumi S. Tanaka, John D. Silverman, Kazuhiro Shimasaku +56
``Little Red Dots'' (LRDs) are an abundant high-redshift population newly discovered by the James Webb Space Telescope (JWST) and considered to be an early growth phase of supermas…
Regular distribution of star formation regions along the spiral arms and rings of disk galaxies
A. S. Gusev, E. V. Shimanovskaya
Last years studies have shown that the spatial regularity in the distribution of young stellar population along the spiral arms and rings of galaxies, previously considered to be r…
WEAVE First Light Observations: Origin and Dynamics of the Shock Front in Stephan's Quintet
M. I. Arnaudova, S. Das, D. J. B. Smith +62
We present a detailed study of the large-scale shock front in Stephan's Quintet, a byproduct of past and ongoing interactions. Using integral-field spectroscopy from the new Willia…
A slow spin to win: The gradual kinematic evolution across metallicities of the proto-Galaxy to the high- disc
Akshara Viswanathan, Danny Horta, Adrian M. Price-Whelan +1
Observational studies are identifying stars thought to be remnants from the earliest stages of the hierarchical mass assembly of the Milky Way, referred to as the proto-Galaxy. We…
X-ray reverberation modelling of the continuum, optical/UV time-lags in quasars
D. A. Langis, I. E. Papadakis, E. Kammoun +2
Context: Extensive, multi-wavelength monitoring campaigns of nearby and higher redshift active galactic nuclei (AGN) have shown that the UV/optical variations are well correlated w…
The impact of cosmic ray heating on the cooling of the low-metallicity interstellar medium
Vittoria Brugaletta, Stefanie Walch, Thorsten Naab +6
Low-metallicity environments are subject to inefficient cooling. They also have low dust-to-gas ratios and therefore less efficient photoelectric (PE) heating than in solar-neighbo…
AGN -- host galaxy photometric decomposition using a fast, accurate and precise deep learning approach
Berta Margalef-Bentabol, Lingyu Wang, Antonio La Marca +1
Identifying active galactic nuclei (AGN) is extremely important for understanding galaxy evolution and its connection with the assembly of supermassive black holes (SMBH). With the…
Core prominence as a signature of restarted jet activity in the LOFAR radio-galaxy population
Dhanya G. Nair, Raffaella Morganti, Marisa Brienza +6
(abridged) Characterizing duty cycles of recurrent phases of dormancy and activity in supermassive black holes in active galactic nuclei is crucial in understanding impact of energ…
On the dynamical evolution of Cepheid multiplicity in star clusters and its implications for B-star multiplicity at birth
František Dinnbier, Richard I. Anderson, Pavel Kroupa
Classical Cepheid variable stars provide a unique probe to binary evolution in intermediate-mass stars over the course of several tens to hundreds of Myr. We studied the binary and…
Spectroscopic confirmation of the galaxy clusters CARLA J0950+2743 at z=2.363, and CARLA-Ser J0950+2743 at z=2.243
Kirill A. Grishin, Simona Mei, Igor V. Chilingarian +6
Galaxy clusters, being the largest gravitationally bound structures in the Universe, are a powerful tool to study mass assembly at different epochs. At z2 they give an unique op…
An Hα view of galaxy build-up in the first 2 Gyr: luminosity functions at z~4-6.5 from NIRCam/grism spectroscopy
Alba Covelo-Paz, Emma Giovinazzo, Pascal A. Oesch +22
The Hα nebular emission line is an optimal tracer for recent star formation in galaxies. With the advent of JWST, this line has recently become observable at z>3 for the first time…
The Pristine survey XXVIII. Journey to the Galactic outskirts: Mapping the outer halo red giant stars down to the very metal-poor end
Akshara Viswanathan, Amanda Byström, Else Starkenburg +14
Context: In the context of Galactic archaeology, the outer halo remains relatively unexplored with respect to its metallicity distribution, merger debris, and the abundance of know…
The spectroscopic binary fraction of the young stellar cluster M17
M. C. Ramírez-Tannus, A. R. Derkink, F. Backs +5
Significant progress has been made toward understanding the formation of massive (M) binaries in close orbits. For example, the detection of a very low velocity d…
The SDSS-V Black Hole Mapper Reverberation Mapping Project: CIV BAL Acceleration in the Quasar SBS 1408+544
Robert Wheatley, Catherine J. Grier, Patrick B. Hall +20
We present the results of an investigation of a highly variable CIV broad absorption-line feature in the quasar SBS 1408+544 (z=2.337) that shows a significant shift in velocity ov…
JWST FRESCO: a comprehensive census of H+[OIII] emitters at 6.8<z<9.0 in the GOODS fields

We present the census of H+[OIII] 4960,5008 Åemitters at 6.8<z<9.0 from the JWST FRESCO survey over 124 arcmin in the GOODS-North and GOODS-South fields. Our unbiased spectr…
Tracing satellite planes in the Sculptor group: II. Discovery of five faint dwarf galaxies in the DESI Legacy Survey
David Martinez-Delgado, Michael Stein, Marcel S. Pawlowski +5
Although substantial progress has been made in reconciling LCDM simulations with the observed abundance and distribution of satellite galaxies, important tensions persist. Studying…
Assessing the accuracy of the star formation rate measurements by direct star count in molecular clouds
Sami Dib, Jian Wen Zhou, Sébastien Comerón +8
Star formation estimates based on the counting of YSOs is commonly applied to nearby star-forming regions in the Galaxy. With this method, the SFRs are measured using the counts of…
