Galaxies with redshifts in the vicinity of A426
We study the global kinematics of the Perseus galaxy cluster (A426) at redshift z=0.017 using a large sample of galaxies from our new MMT/Hectospec spectroscopic observation for... -
The UNCOVER phot. catalog of A2744 with HST+JWST
In 2022 November, the James Webb Space Telescope (JWST) returned deep near-infrared images of A2744-a powerful lensing cluster capable of magnifying distant, incipient galaxies... -
SEAMBHs XII. Reberberation mapping for 15 PG QSOs
In this work, we present the first results of the long-term high-cadence spectroscopic monitoring of 15 PG quasars with relatively strong FeII emission, as a part of a broader... -
DESI observations of the Andromeda galaxy
We present Dark Energy Spectroscopic Instrument (DESI) observations of the inner halo of M31, which reveal the kinematics of a recent merger-a galactic immigration event-in... -
SEAMBHs. XI. Mrk 142 X-ray to optical light curves
We performed an intensive accretion disk reverberation mapping campaign on the high accretion rate active galactic nucleus Mrk142 in early 2019. Mrk 142 was monitored with the... -
SEAMBHs. X. Reverberation mapping campaign compilation
We compiled a sample of 73 active galactic nuclei (AGNs) with reverberation mapping (RM) observations from RM campaigns, including our ongoing campaign of monitoring... -
SEAMBHs IX. 10 new H{beta} light curves
As one paper in a series reporting on a large reverberation mapping campaign of super-Eddington accreting massive black holes (SEAMBHs) in active galactic nuclei (AGNs), we... -
SEAMBHs. V. The third year
This paper reports results of the third-year campaign of monitoring super-Eddington accreting massive black holes (SEAMBHs) in active galactic nuclei (AGNs) between 2014 and... -
SEAMBHs IV. H{beta} time lags
We have completed two years of photometric and spectroscopic monitoring of a large number of active galactic nuclei (AGNs) with very high accretion rates. In this paper, we... -
SEAMBHs. II. Continuum and Hbeta LCs
This is the second in a series of papers reporting on a large reverberation mapping (RM) campaign to measure black hole (BH) mass in high accretion rate active galactic nuclei... -
SEAMBHs. I. Mrk 142, Mrk 335, and IRAS F12397+3333
We report first results from a large project to measure black hole (BH) mass in high accretion rate active galactic nuclei (AGNs). Such objects may be different from other AGNs... -
0446+11 15GHz VLBA images in Stokes I, Q, U
The physical mechanisms driving neutrino and electromagnetic flares in blazars remain poorly understood. We investigate a prominent multimessenger flare in the quasar PKS... -
Milky Way as seen by classical Cepheids. I. WISE
Classical Cepheids are the archetype of the standard candle, thanks to the period-luminosity relation, which allows us to measure their intrinsic brightness. They are also... -
Extended cluster radio sources catalog
The radio jets of radio galaxies in galaxy clusters are often bent due to the ram pressure of the intracluster medium. Most studies of bent radio tails initially identified... -
Spectroscopic redshift survey of the Coma cluster
We study the physical properties of weak-lensing subhalos in the Coma cluster of galaxies using data from galaxy redshift surveys. The data include 12,989 galaxies with measured... -
CL-AGN from the DESI. II. Stat. properties from DR1
We present the identification of changing-look active galactic nuclei (CL-AGNs) from the Dark Energy Spectroscopic Instrument First Data Release and Sloan Digital Sky Survey... -
CIGALE intermediate redshifts Type II QSOs cand.
Active galactic nuclei (AGNs) play a vital role in the evolution of galaxies over cosmic time, significantly influencing their star formation and growth. As obscured AGNs are... -
Pristine-Gaia follow-up of EMP stars
We present the first spectroscopic follow-up of bright (G<15) and distant (up to 35kpc) very and extremely metal-poor (V/EMP, [Fe/H]<-2.5) red giant branch stars from the... -
Galactic center maser-bearing Miras
This sample of 370 Mira variables that are likely near the Galactic center (GC) has been selected from the OGLE and BAaDE surveys based on their sky coordinates, OGLE... -
