  We present the results of the single-dish observations using the Korean VLBI
Network to search for anomalous microwave emission (AME) in nearby galaxies.
The targets were selected from MApping the dense moLecular gAs in the sTrongest
stAr-formiNg Galaxies (MALATANG), a legacy survey project of the James Clerk
Maxwell Telescope. The MALATANG galaxies are good representatives of local
galaxies with enhanced nuclear activity associated with star formation and/or
AGN, providing IR-bright galaxy samples; thus, they are good candidates for AME
hosts. Combining with the ancillary data, we investigated the radio-IR spectral
energy distribution (SED), while searching for the AME signals in five
galaxies. The AME in NGC 2903 was well detected at a significant confidence
level, whereas that in NGC 2146 and M82 was marginal. NGC 1068 and Arp 299
indicated no significant hints, and we provided the upper limits for the AME.
The best-fit SED exhibited local peaks of the AME components at higher
frequencies and with stronger peak fluxes than those in the previous studies.
This suggested the origin of AME being denser environments such as molecular
clouds or photodissociation regions rather than warm neutral/ionized medium as
commonly suggested by previous studies. Further, our AME-detected targets were
observed to exhibit higher specific star-formation rates than the other
extragalactic AME hosts. Furthermore, AME favored starburst galaxies among our
sample rather than AGN hosts. Consequently, this might imply that AGNs are
excessively harsh environments for tiny dust to survive.
