Mapping the Milky Way with Gaia Bp/Rp spectra-IV: the broken and asymmetric density profile of the stellar disk traced by a large sample of red clumps
Wenbo Wu, Yuqin Chen, Jianhui Lian +10
This study explores the density profile of the stellar disk, radially and azimuthally, based on approximately 8.4 million red clump stars selected from Gaia Bp/Rp spectra. After co…
Constraints on CMBR flux due to high-z dust emission
Martin Lopez-Corredoira
Gjergo & Kroupa (2025) have proposed a new foreground CMBR component produced by dust associated with the progenitor clouds at that led to the formation of massive early-…
Improved measurements of the age of JWST galaxies at z=6-10
M. Lopez-Corredoira, C. M. Gutierrez
From James Webb Space Telescope (JWST) surveys, 31 galaxies with average redshift 7.3 are selected containing large Balmer break, Lyman- break (V-shaped SED versus ). Apart f…
Underestimation of Hubble constant error bars: a historical analysis
Martin Lopez-Corredoira
An analysis of a historical compilation of Hubble-Lemaître constant values (: 163 data points measured between 1976 and 2019) assuming the standard cosmological model gives a…
Measuring the Time Variation of the Fine-structure Constant with Quasars Detected by LAMOST
Jin-Nan Wei, Rui-Jie Chen, Jun-Jie Wei +2
The [O III] emission lines in the optical spectra of galaxies and quasars have been widely used to investigate the possible variation of the fine-structure constant…
Galaxy Ages with Redshift z=2-4: Stellar Population Synthesis for Candidates in FourStar Galaxy Evolution Survey
Chong-yu Gao, Martin Lopez-Corredoira, Jun-jie Wei
Observations of large amount of massive galaxies with relatively old populations found at high redshifts are challenging galaxy formation scenarios within standard cosmology. Preci…
Age of massive galaxies at redshift 8
M. Lopez-Corredoira, F. Melia, J. -J. Wei +1
Recent James Webb Space Telescope (JWST) data analyses have shown that massive red galaxies existed at redshifts , a discovery that is difficult to understand in the context o…
The Hubble Tension Survey: A Statistical Analysis of the 2012-2022 Measurements
Bao Wang, Martín López-Corredoira, Jun-Jie Wei
In order to investigate the potential Hubble tension, we compile a catalogue of 216 measurements of the Hubble--Lemaître constant between 2012 and 2022, which includes 109 mo…
Edwin P. Hubble, astropolítico
Martin Lopez-Corredoira
Rather than offering chronologically ordered encyclopedic knowledge of a lifetime, only some of the most striking events of the existence of this well-known scientist are here poin…
Analysis of the Amplitude of the Sunyaev-Zel'dovich Effect out to Redshift z=0.8
M. Lopez-Corredoira, C. M. Gutierrez, R. T. Genova-Santos
The interaction of the cosmic microwave background (CMB) with the hot gas in clusters of galaxies, the so-called Sunyaev--Zel'dovich (SZ) effect, is a very useful tool that allows…
Stellar content of extremely red quiescent galaxies at z>2
M. Lopez-Corredoira, A. Vazdekis, C. M. Gutierrez +1
CONTEXT. A set of 20 extremely red galaxies at 2.5<z<3.8 with photometric features of old passive-evolving galaxies without dust, with stellar masses of ~10^{11} M_sun, have colors…
The young open cluster NGC 7067 using Strömgren photometry
M. Monguió, I. Negueruela, A. Marco +13
NGC 7067 is a young open cluster located in the direction between the first and the second Galactic quadrants and close to the Perseus spiral arm. This makes it useful for studies…
Dust in clusters: separating the contribution of galaxies and intracluster media
C. M. Gutierrez, M. Lopez-Corredoira
We have analized a sample of 327 clusters of galaxies spanning the range 0.06-0.70 in redshift. Strong constraints on their mean intracluster emission by dust have been obtained us…
Peaks in the CMBR power spectrum. II. Physical interpretation for any cosmological scenario
Martin Lopez-Corredoira
In a previous paper (part I), the mathematical properties of the cosmic microwave background radiation power spectrum which presents oscillations were discussed. Here, we discuss t…
