Planetary nebulae as tracers of stellar population properties: unlocking their potential with integral-field spectroscopy
Ana Ennis, Johanna Hartke, Magda Arnaboldi +3
Planetary nebulae (PNe) are essential tracers of the kinematics of the diffuse halo and intracluster light where stellar spectroscopy is unfeasible, due to their strong emission li…
XQz5: A New Ultraluminous z5 Quasar Legacy Sample
Samuel Lai, Christopher Onken, Christian Wolf +2
Bright quasar samples at high redshift are useful for investigating active galactic nuclei evolution. In this study, we describe XQz5, a sample of 83 ultraluminous quasars in the r…
Dwarf galaxies show little ISM evolution from to : a spectroscopic study of metallicity, star formation, and electron density
John Pharo, Yicheng Guo, Guillermo Barro Calvo +6
We present gas-phase metallicity measurements for 583 emission line galaxies at , including 388 dwarf galaxies with , and explore the de…
MAGNIF: A Tentative Lensed Rotating Disk at detected by JWST NIRCam WFSS with Dynamical Forward Modeling
Zihao Li, Zheng Cai, Fengwu Sun +39
We report galaxy MACS0416-Y3 behind the lensing cluster MACSJ0416.1--2403 as a tentative rotating disk at detected through its [OIII] emission in JWST NIRCam…
Virial Black Hole Mass Estimates of Quasars in the XQ-100 Legacy Survey
Samuel Lai, Christopher A. Onken, Christian Wolf +4
The black hole (BH) mass and luminosity are key factors in determining how a quasar interacts with its environment. In this study, we utilise data from the European Southern Observ…
XQR-30: Black Hole Masses and Accretion Rates of 42 z>6 Quasars
C. Mazzucchelli, M. Bischetti, V. D'Odorico +19
We present bolometric luminosities, black hole masses and Eddington ratios for 42 luminous quasars at z>6 using high signal-to-noise ratio VLT/X-Shooter spectra, acquired in the en…
XQR-30: the ultimate XSHOOTER quasar sample at the reionization epoch
Valentina D'Odorico, E. Banados, G. D. Becker +46
The final phase of the reionization process can be probed by rest-frame UV absorption spectra of quasars at z>6, shedding light on the properties of the diffuse intergalactic mediu…
An Escaping Outflow in a Galaxy with an Intermediate-mass Black Hole
Zhiyuan Zheng, Yong Shi, Fuyan Bian +5
While in massive galaxies active galactic nuclei (AGN) feedback plays an important role, the role of AGN feedback is still under debate in dwarf galaxies. With well spatially resol…
Identification of Bubble Nebulae around NGC 55 ULX-1 with MUSE Observations
Changxing Zhou, Hua Feng, Fuyan Bian
Using the Multi Unit Spectroscopic Explorer (MUSE) instrument on the Very Large Telescope, we identified three bubble nebulae (denoted as A, B, and C) around an ultraluminous X-ray…
Effects of the Hunga Tonga-Hunga Ha'apai Volcanic Eruption on Observations at Paranal Observatory
Robert J. De Rosa, Angel Otarola, Thomas Szeifert +8
The Hunga Tonga-Hunga Ha'apai volcano erupted on 15 January 2022 with an energy equivalent to around 61 megatons of TNT. The explosion was bigger than any other volcanic eruption s…
Identification of a Helium Donor Star in NGC 247 ULX-1
Changxing Zhou, Hua Feng, Fuyan Bian
With Very Large Telescope (VLT) Multi Unit Spectroscopic Explorer (MUSE) observations, we detected highly variable helium emission lines from the optical counterpart of the superso…
The Emergence of Brightest Cluster Galaxy in a Protocluster Core at
Dongdong Shi, Xin Wang, XianZhong Zheng +4
We report the detection of a pair of massive quiescent galaxies likely in the process of merging at the center of the spectroscopically confirmed, extremely massive protocluster BO…
Characterising SMSS J2157--3602, the most luminous known quasar, with accretion disc models
Samuel Lai, Christian Wolf, Christopher Onken +1
We develop an accretion disc (AD) fitting method, utilising thin and slim disc models and Bayesian inference with the Markov-Chain Monte-Carlo approach, testing it on the most lumi…
