LMC eccentric ellipsoidal red giant binaries
Modelling ellipsoidal variables with known distances can lead to exact determination of the masses of both components, even in the absence of eclipses. We present such modelling... -
High-mass starless clumps from ATLASGAL & SEDIGISM
In order to study the initial conditions of massive star formation, we have previously built a sample of 463 high-mass starless clumps (HMSCs) across the inner Galactic plane... -
HST/WFC3 phot. of the S1-SX images of SN Refsdal
In late 2014, four images of supernova (SN) "Refsdal," the first known example of a strongly lensed SN with multiple resolved images, were detected in the MACS J1149... -
GW200224_222234 follow-up survey with Subaru & GTC
The LIGO/Virgo detected a gravitational wave (GW) event, named GW200224_222234 (also known as S200224ca) and classified as a binary-black hole coalescence, on 2020 February 24.... -
High-z galaxies from JWST ERO
This paper highlights initial photometric analyses of JWST NIRCam imaging data in the sightline of SMACS0723, aiming to identify galaxies at redshift z>7. By applying a... -
SDSS magnetic white dwarfs rich in hydrogen
White dwarfs are excellent research laboratories as they reach temperatures, pressures, and magnetic fields that are unattainable on Earth. To better understand how these three... -
Monitoring of the neutron star XRB Centaurus X-4
We report on a long-term optical monitoring of the neutron star X-ray binary Centaurus X-4 performed during the last 13.5yr. This source has been in quiescence since its... -
Gravitational-wave frequencies between 300-500Hz
Continuous gravitational waves are nearly monochromatic signals emitted by asymmetries in rotating neutron stars. These signals have not yet been detected. Deep all-sky searches... -
2015-2017 LIGO obs. analysis for 221 pulsars
We present a search for gravitational waves from 221 pulsars with rotation frequencies >~10Hz. We use advanced LIGO data from its first and second observing runs spanning... -
SPT-SZ clusters with optical & X-ray data
We derive cosmological constraints using a galaxy cluster sample selected from the 2500deg^2^ SPT-SZ survey. The sample spans the redshift range 0.25<z<1.75 and contains... -
BVI LCs and radial velocities of PSR J1306-40
PSR J1306-40 is a millisecond pulsar (MSP) binary with a non-degenerate companion in an unusually long ~1.097 day orbit. We present new optical photometry and spectroscopy of... -
Mass accretion rates of PMS stars. VI. LH95 in LMC
We report on the accretion properties of low-mass stars in the LH 95 association within the Large Magellanic Cloud. Using noncontemporaneous wideband optical and narrowband... -
5GHz TMRT observations of 71 pulsars
We present integrated pulse profiles at 5GHz for 71 pulsars, including eight millisecond pulsars (MSPs), obtained using the Shanghai Tian Ma Radio Telescope. Mean flux densities... -
Narrow absorption lines of lensed QSO J1029+2623
We exploit the widely separated images of the lensed quasar SDSSJ1029+2623 (z_em_=2.197, {theta}=22.5") to observe its outflowing wind through two different sightlines. 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... -
The BOSS emission-line lens survey. III.
We introduce the Baryon Oscillation Spectroscopic Survey (BOSS) Emission-Line Lens Survey GALaxy-Ly{alpha} EmitteR sYstems (BELLS GALLERY) Survey, which is a Hubble Space... -
VLT/MUSE spectroscopic obs. of MACS J1149.5+2223
We present Multi Unit Spectroscopic Explorer (MUSE) observations in the core of the Hubble Frontier Fields (HFF) galaxy cluster MACSJ1149.5+2223, where the first magnified and... -
VLA, ALMA and SMA monitoring of Sgr A*
We report new observations with the Very Large Array, Atacama Large Millimeter Array, and Submillimeter Array at frequencies from 1.0 to 355GHz of the Galactic Center black... -
HST lensing analysis of the CLASH sample
We present results from a comprehensive lensing analysis in Hubble Space Telescope (HST) data of the complete Cluster Lensing And Supernova survey with Hubble cluster sample... -
HST/WFC3 observations of z~7-8 galaxies in A2744
Exploiting the power of gravitational lensing, the Hubble Frontier Fields (HFF) program aims at observing six massive galaxy clusters to explore the distant universe far beyond...
